The smaller the market CAP the higher the returns. Even if they have good website and not really world changing product it will still atleast get 50-100K. Thats how things work in crypto !!!
This is not certain about that lower the price higher the return . If the coin is good and even if the price has gained in few months still it aha the future and it will rise quickly even if it falls to some extent . For the coins with very less value those may not be able to rise only and this you will lose out the money in such cases . So better invest in right coin with good prospects .
