First tip - BTC is not going back to 3k this year
second tip - buy in increments when it dips hard. BTC still has a long way to go before it reaches its peak this year.
third tip - Do your OWN research. Don't rely on others.
4th tip - Join some FB groups in order to find out more about crypto and what coins are hot right now.
5th tip - look at Medium articles (like mine at cryptoaccountbuilders) and learn.
A small tip from me is that fomo should not be able to access altcoin for several weeks in just 1-2 weeks, because I'm sure you'll easily lose money when buying altcoin like that
