Investing in those altcoins are just launching is alway risky, but some of them are also full of profitable, risk and reward always coexist, people brag their project is quite normal, but it dont means we believe it, anyway, buying new currency should have the consciousness that lose all of the money.
i don not have enouth guts, so i only just invest in those altcoins with high market value.
Yes, in new altcoins there is a big advantage if in the future there is a pump, the profit is directly proportional to the risk it carries. It is safer to invest in coins that have shown their quality and are able to compete in the crypto market and even last for a long time.
