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.
If you are a trader then you should try selling and buyback Bitcoin in order to take advantage of the market fluctuations. There is another option though, you can gamble on a casino (this is not the best way to invest because you might end up owing nothing and lose all your investment) or there are some casinos I think which you invest on them and you somehow become the House. I am not sure if this still exist but I heard of someone in a conference that this is his shot of investing his cryptos.
