I'm just getting back into Crypto after a long time, during which I've forgotten a lot of stuff.

If I have $1000 in my trading account and I want to risk $20 on a trade (with no stop) and plan to make $100 on that trade, how do I figure out the amount of altcoins I should buy?

Then, how do I calculate where I need to exit to make $100?

Appreciate the calculation help,
