In my opinion you should use your money to invest in the three things only .
First thing is to buy a miner for ETH , BCH like coins because mining for such types of coins is a better option because profit is better in these coins .
Second thing is to launch your own coin with better economical support and better promotion , because launching of the coin needed only money and devloper only and simple other things we can hire from online marketplace directly .
Third thing you should do , is to make trading yourself , because I don't think that there us another way to make money by rotation of money from exchange to exchange in small small amount .
So if you will go through these ways then surely will get not success but a better success .
