I have got a few spare bitcoins.Please suggest a trustworthy site where I can invest them for some profit.
Edit: A lot of posts here are about reminding me to keep holding bitcoin and it is itself an investment. I agree with this but what I meant to ask was the ways to grow my bitcoin holdings. For example, If I have 1 BTC today and I do nothing with it, it will remain 1BTC after 10 years. I wanted to know if there were any legit ways by which we could get profits on our existing bitcoin holdings.
In my opinion money is the only way to make money. Specifically Bitcoin prices and Altcoins are very cheap and especially Altcoin is ETH for only $ 218 and the amount of 1BTC you invest in ETH is reasonable. I do not think it will take much time and you will be earning profits much higher than it is now. So buy ETH and follow it on coinmarketcap is the best.
