I know that it varies from people to people and their strategies but there must be some important and basic points which people tend to forget all the time .
Of course I don't want you to reveal your trading strategy but some good tips that would really help me out.
First of all, leave day trading to the bots! Go for longer term trades on recently heavily dumped coins. Don't diversify too much, and don't buy small amounts of a lot of coin. You will end up only with scraps. Concentrate on few well researched coins instead. Hunt down coins with solid, new technology and buy the dips.
And stay away from pump groups. The good ones are closed clubs with rather high buy-in price.
If he can hunt it or narrow it down. But we know we dont know a hard coin that will have solid future in the crypto world. There are many candidates to have a solid investment but for starters it would be risky to do that.
