i think bitcoin now is not good to invest. but i believe bitcoin will raise up again, and more strong. we just need to join on time
I think so too. This is just the same as with other types of investments. There happen to be falls and rises. One only got to observe the situation to see the right moment to get in and out.
We do not have any reason not to believe in crypto currency because for those who think it is bubble and so it has fallen in value are wrong as every year price dips and then rises and it is the fact that it exists from past 10 years and not just 1-2 years. Also those who want to make money will start investing in this market as it is almost at lower price of this year and make money with the price increase.
