No forum will help you in investing in altcoins, only you can do it yourself. People invented the abbreviation DYOR for a reason. It completely captures the essence of your topic. If you want potential altcoins for the next bull run, then do your own research, no one will help you and voice promising altcoins. Such information is extremely valuable and if it is freely distributed on various forums, it immediately becomes trash. This applies to any advice on investing in a particular altcoin. In investing you have no helpers or friends, only your own head and your own analytics are your best friends in the crypto market.
To find out all that, it is necessary to learn about how to do research, so that they can find their own Altcoin and they trust it. Suggestions from other people are not justified, it will only be a reference. When someone suggests getting in on a particular altcoin, rest assured he or she has a hold on it first. Your own choice will be your own responsibility. The top altcoin potential won't be either. Remember that FTX is the top Altcoin and we all know in the end FTX has a criminal CEO who uses all investors money.
To find out, you need to constantly analyze and study the altcoin industry and make calculations. Few people want to do this, it is easier to go to some community and ask to provide some altcoins for successful investment.
Unfortunately, in most cases such lazy ways of investing end up with a complete loss of money. If an investor doesn't know where to invest his money correctly, he also doesn't know when exactly to fix the profit from the investment. Most often, altcoin investors buy altcoins and stay with them, only at a greatly reduced price. Far below the price at which they bought them.
