Over the last couple days in an effort to figure out how to find my POAP raffle ticket (see prior post), I used an online service called mycrypto.com which is listed as one of the many supported online wallets on Trezor's website; so I felt confident in knowing that it's a legit website.

The interface is rather slick (a little bit too much) and it may be useful for someone that holds a variety of cryptocurrencies. But for someone who only has fewer than five, I think the Trezor Suite is perfectly fine. However, Trezor Suite may not support your cryptocurrency and MyCrypto may. I like the fact that data is not stored on their servers, rather it is stored locally, and users have the ability to easily delete the local data.

I still cannot figure out how to view ERC721 in an online wallet. Please comment below if you know how.

I had this question in my mind today and did some research on this topic.

ERC20

Ethereum is very versatile and allows other types of altcoin to be built on top of it (e.g., BAT). ERC20 is this standard. Anything that is fungible and built on Ethereum is using ERC20. If you would like to see what other coins use the ERC20 standard, you can go to the Trezor website. There are literally hundreds of them. You can also view ERC20 coins in your wallets.

ERC721

Anything that is non-fungible (e.g., one of a kind type stuff), is built using the ERC721 standard. These are starting to get very popular. The most common ones are NBA Topshot and Beeple's artwork that sold for $69 million. So far, I'm not aware of any wallet that supports ERC721 so you cannot view your ownership that way.

Let me know if you have any questions or follow-ups. I find this topic very fascinating. If someone knows how ERC20 rewards ETH holders, please share. I don't think someone who trades BAT is actually paying a ETH fee when transacting but I may be wrong.

I spent the better half of my morning trying to figure out how ERC-721 works. If someone has an ELI5 (Explain Like I'm 5) summary, I would appreciate reading about it.

CoinGecko is running a raffle where users can redeem their "coins" (daily rewards for logging into the website) into a raffle ticket. I did just that and followed the link to POAP.xyz, which is a website dedicated to crypto badges. Users of POAP get rewarded with an NFT recognizing their attendance to an event. However, in order to get the attendance NFT, you need an Ethereum address. I'm not sure how POAP works because I can't see it in my Trezor Suite Wallet but the attendance NFT did indeed transfer over. 

There's a second step to enter into the actual raffle itself. I had to download MetaMask (an online wallet extension) to receive the attendance NFT then enter into the contest.

For a complete newb, like me, this is a lot of steps and very confusing every step of the way. I hope there is a more elegant solution to this because the ideas are very compelling.

I am enjoying using Brave as my primary browser. In fact, I have four browsers installed (in order of usage from highest to lowest):

1. Brave - Recently began using it. I like the fact it is based off of Chromium so it has a wide range of compatibility with existing extensions and websites 
2. Firefox - My previous main browser but I found that a handful of websites would break. Perhaps it's because of conflicts with my extensions, but I like using many of the privacy enhancing extensions that are available. Not being owned by a giant tech company gives it extra points
3. Chrome - I mainly use this when reading news articles because of this extension which bypasses paywalls
4. Internet Explorer - Mainly used to confirm a broken website. In very rare cases my Brave extensions break a website and I use IE to validate that the website is indeed not working and that it's not on my end

The extensions that I use in Brave are (in no particular order):

• Bitwarden - Password manager. I migrated from LassPass when they raised their price and reduced features for the free tier. I pay Bitwarden $10 / year to support app development but they also offer a very feature rich free option that I highly encourage everyone to use
• ClearURLs - Cuts the tracker clutter in URLs
• Google Dictionary 
• Google Translate
• Imagus - As a Redditor, this is a must have. Enlarges images so you don't need to click links, just hover over links
• OneTab - I love opening lots of tabs. This is a life saver. You can also share a group of tabs via a link to others
• PixelBlock - Supposedly blocks "read receipts" in Gmail
• Privacy Badger - Created by EFF to reduce online trackers
• Pocket - Great to save websites for later and read either on your phone, tablet or Kobo
• uBlock Origin - I think everyone needs this. Very effective ad blocker
• Ugly Email - Also blocks read receipts in Gmail, but catches trackers that PixelBlock doesn't

I recently read an article by the Washington Post in which they had a link explaining what a hardware wallet is. The article does a fantastic job of explaining the benefits and vulnerabilities of a hardware wallet to newbies. Many newbies buy a hardware wallet not knowing how to use it, and worse still, think they're protected simply by virtue of owning one without realizing the vulnerabilities ("with great powers, come great responsibilities").

I think storing a minimal amount on an online exchange is fine, but if you are planning to hold for a while then a hardware wallet is a must buy. What makes a hardware wallet superior? Unlike an online wallet that is connected 24/7 and anyone can access it from anywhere (including a hacker), a hardware wallet only works when the physical device is connected to the computer. The most important thing to remember about a hardware wallet is to NEVER GIVE OUT YOUR SEED PHRASE. 

The victims in the article purchased a hardware wallet only to lose all their bitcoins because they gave our their seed phrase to a fake iOS app. Trezor, a popular hardware wallet, does not and has no plans to develop a mobile app. My heart broke when I read that one victim lost $600,000 in bitcoins. That's an expensive lesson and I hope you don't make the same mistake.
