If you have around 1.5k usd to invest then invest in various digital currencies at the rate of around 50 USD per investment and maybe 200 in Bitcoin and 200 in Ethereum. I would main,y invest that money in the infrastructure blockchain coins which are the sprinting board for other projects and services. Having a varied portfolio of around 20 to 40 coins and projects will help diversify your risk as well as your assets. I hope you do good research in order to get the best deal for your money, good luck!
