The best tip is that before investing take your time in studying the market. Do not blindly put your money. Learn how to analyse the market and test the market with small capital. Then, take bigger risks as you gain experience.
Well as long as new people who want to invest in the long term do not invest their money in shit coins then I guess it will be alright since we can pick top coins on coinmarketcap like ETH and BNB. Never FOMO because other people invest in that project because there's a chance that's a scam project and don't forget to use money that we can afford to lose.
