Very informative post. I'd just like to add one thing about trading cryptocurrencies. It is very easy to get emotional when the prices skyrocket or when they crash but if you try to change your mindset it will help a lot.
When you see a crash you tend to be scared to buy, because everything looks so red :) but now imagine that instead of the price of bitcoin, it was the price of iPhone 7 that dropped. Would you be scared to buy it? Hell no, it's on sale!
So my strategy is nothing fancy, just commonsense buy low sell high.
