If you already have more money then you can invest in cryptocurrency. you can choose bitcoin or altcoins. Make sure the investment you make is for the long term. Because of that, it might reduce the risk. That's just my opinion.
If the money is an issue, invest in Bitcoin because it would be kind of logical that the coin will be worth more than any altcoin.
surely bitcoin is the best one to get big profits in the long run, because the longer we get the more benefits because bitcoin has great potential in price increases
