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.
There are no businesses currently supporting hold bitcoin to receive monthly bitcoins. We can only buy more or you can sell bitcoin at a high price and then buy it again when its price is dumped. Your bitcoin number will increase but not much. You should buy more.
