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.
Nobody is saying instant millionaire, what im talking about is getting in early, then waiting a reasonable amount (4 years is reasonable if what you get in return is retirement type of money)
The problem is, I dont see a single altcoin worth holding for 4 years. In fact, I have serious doubts in most altcoins still being here in 4 years.
Etherum? Monero? Those two have significant market cap and fundamentals. Personally I think Decred, Potcoin, and ICONOMI as well. But XMR and ETH are some very safe picks. Litecoin is probably the second oldest crypto and it's still around so there's definitely some staying power for it. What are your critiques for picking an altcoin?
