But the time where you will have a winning rate of 1000% or more in a short time is likely gone! Nevertheless, some altcoins delivered such high winning rates this year and there will be surely the one or other altcoin that you can buy or mine very cheap now with the potential to have high winning rates in future.
1000% is not that much man. That is only 10x the current price. Therefore if you buy a Bitcoin today, and it goes up to $75,000 it means you made 1000% return on your initial investment. I personally think Bitcoin is going to be worth over $750,000 someday which means you will make 10,000% ROI if you invest right now.
