What are the four crypto currencies that I should buy and keep untouched for at least five years?
You can do that with any coin, even Bitcoin. I will even advise you to do that with Bitcoin now that the price is stable at $6000. A time will come when it wont be at this price any longer and will have a higher price than this. So if you want to buy and hold for long, this is the right time. You can also buy Ethereum and Litecoin, including other altcoins that are trending.
