My advice to anyone trying to make a lot of money in cryptos right now, is to invest into smaller value alt coins that have a potential to explode.
I think knowledge and psychological preparation are essential before you invest in crypto like bitcoin. You can divide the percentage accordingly to invest. You can invest half of your capital in bitcoin and invest in other virtual currencies. But you should focus on investing in one or two other virtual currencies. Do not invest too many different virtual currencies. It takes a lot of time to manage and monitor the value which profit is less.
