The days of becoming an instant millionaire are pretty much over.
The people that are making lots of money on crypto right now are the ones that already have it.
Whales are manipulating the price of coins and raking in the profits as the little fish try to make a few dollars.
I think Crypto still has lot of potential for new investors also. You can invest in a brand new Coin though ICO and if that coins make good than ofcourse you can earn a lot of profit by trading in exchanges. Even buying Bitcoin today in big quantity can result in double the profit in a year or two.
Any thing can possible but at the same time we have to think about negativity also. ICO is good option to invest but today we are seeing many ico failed in beginning only. We have to check both sides of the coin like head or tail, either we will make or may loose.
