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.
Instant millionaire has/never been a thing... unless you win the lottery. Even with Bitcoin and it's like 9000% return from the beginning of inception to 2013, it still took 4 years. Just a little perspective to be aware of in response to your pessimistic view.
