Either your a trader or an investor, not both. If you have a weak stomach for big dips, you have too much money on the table.
Trading involves a lot of experience and know how that you don't learn overnight. My opinion is that most people lose money trading.
If you just can't resist the crypto markets, then only buy what you can afford to lose.
If you insist on trading, the first thing is to learn how to read a chart, it's amazing what it can tell you.
