There are many coins that until last month were costing half of what they are now, such as $XRP and $ADA . If you had invested a good amount, you would certainly have double the amount invested. There are others that there is no point in buying because the ones who control them are the whales. They make them fall and then buy when they are in the shit and then they rise to the heights and they sell. Be quicker than these whales. This is an important tip. The only one in the world that whales cannot control is $BTC , since its market value exceeds 1 trillion reais. BE QUICKER THAN THEM, trust me.
