ask yourself what you really want to do.
you need to accept these things:
- trading altcoins is very risky
- altcoin market is very manipulated
- you can lose a lot of money but you can also earn a lot too.
- it will require a lot of time to learn and a lot of time to study and trade.

if you are ready to do all this and accept the risks that comes with them then you are ready to become a trader.
i say "trader" instead of "investor" that you used because i believe investment in altcoins is not really a good choice but rather trading them is the better choice that you can be more successful in.
