I think we should always doubt and hesitate when we want to invest because with that doubt, we will find out and make a research about the project we want to invest unless that investment is bitcoin. The number of altcoins is currently more than 2000 and many do not have daily transactions because there is no liquidity in the market and we should do research before investing.
avoid investing in altcoins like that. investing in altcoins that do not have daily trading will waste our money. doubt for all altcoins and even bitcoin is necessary, because what we see is a trade. we can lose the moment to sell or buy, and it will make a regret.
