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.
No doubt it is, we know bitcoin is one of best coin and it has good potential more than all other coin the reason for this is, bitcoin is first crypto currency and it being consider a king coin, so everyone is using it for their own benefit but bitcoin itself can grow as billions of people are happy to invest in this bearish as they are sure future of crypto currency is really bright.
