Hello, first thing that you would do is to read read and read about crypto currency. since there are thousands of cryptocurrencies out there, you must check coin market if it is listed. Then you may start buying some if you wish to buy bitcoin as the leading crypto, or you may pick ethereum or litecoin where we know they are most stable now then thats great, you may invest and do tradings. Or you can also do buying and selling, buy crypto with low price then wait for a while till value rises then if you desire to sell you can sell and you can earn.  May you have a  successful business with crypto.
