....So, during the bear market, employ your time opening accounts in as many exchanges as you can, verify as needed, learn their UI, etc... During a bull market things happen very fast, and chances are that you won't be able to use that exchange you need to trade some fork/altcoin or use for fiat withdrawal if you have not done your homework well in advance.....
This is great advice.
The bear market will be long and tough to endure, and this is just the sort of work that will be making progress, instead of anxiously watching falling or stagnant prices.
Verification can often be a long process. It is also useful to be familiar with the rules of the exchanges and businesses you deal with.
