Cryptocurrencies only at the first stage of their historical development. There will be ups and downs - this is a fact.
But we support the blockchain, right?

I think that investing in crypto currency is a good future, the development of crypto currencies depends on the investor itself, whether it is bad or not depending on the intention and purpose of investing.
that's not fully true.if we compare bitcoin with another existing coins, bitcoin developing no need any investor's money.they didnt held ico at all but in the fact bitcoin was be the main cryptocurrency.its depend on developers spirit to build their coins.
