If I have $10000 I will buy several coins like half of bitcoin, Ethereum, and Litecoin. These are the best coins in the market and in the future, I am sure they will give me huge money. And With some money, I will fill the hobbies of my mind.
The market is down. It is very risky now to invest a LOT of money in the cryptocurrencies, especially if you are a newbie. Probably, it will be better to think about opening some small business.
