Investing in bitcoin is a clever decision now because very soon it's price and demand will increase as both are directly dependent on each other. So if you but bitcoin and hold got 6 months then also you could get $100 just by doing nothing but hold your $800. I think it's not a bad idea
However, the price will not always move based on our prediction, there are times that it falls back and we can lose our investment if we sell for a cheaper price. I guess it is all about spotting the right timing and now is the right timing since the price has risen and continuously rising.
Think that we will get to the $1,000 in the next few days, that should be your inspiration to your investment now.
