How high is the risk?? As in 10% or 90%? Just want to get my facts straight.. thx for ur help
Risk is closer to 100%
That said risking 100% to make 30x (using your $600,000 profit estimate) is a good risk/reward but don't bet/risk that much unless you can afford to lose 100%
If you are new to the crypto world I would stick to established coins that have been around for awhile, you'll see a lot of coins like this come and go so you'll be able to better assess the risk involved.
As for Hodl specifically the coins market cap is only $53,000
https://coinmarketcap.com/currencies/hodlcoin/ An investment of $20k would drive the price for each con through the roof, and as soon as you were done buying the price would collapse again. It would take you awhile to accumulate $20k worth of coins at the current market price.
