nice article, enjoy your merit
perhaps you can also mention the way you store your keys offliine, that's something I have been pondering recently. How many back ups to do and where to put them.
I have a lot of altcoins and tokens because I believe it's just the beginning of a multi-year bull market for crypto. The tech is so revolutionary that it's a no-brainer to invest at some of the most promising projects.
Now the problem is each of these tokens started with small or of little value. But after a year (from early 2017), they already amount to $100k plus. It's quite risky to leave them in an exchange or even on a single ETH wallet (because many are ETH tokens).
So basically, what I did is spread the risk or avoid putting all my eggs in one basket for a thief to steal. Imagine one slip up and all your wealth gone.
1. Use hardware wallets for the most valuable coins. (Trezor)
2. Never use those deterministic wallets for ETH and ETH tokens - a thief only needs to steal your 12 word seed and he has all the coins in all those addresses. Use independent addresses for each type of token.
3. I print out private keys on paper, split into two parts (so two pieces of paper), stored into two different locations.
Anyway, the key objective is to diversify security.
FYI, 2FA all your crypto-related email, the world is a more dangerous place than 5 years ago.
And never never tell anyone you got hundreds of thousands dollars worth in your flash drive. You could also be robbed at gun point.
