I read some news this last week, and there is some indication of wash trading and spoofing going on, so the prices are dropping.
Do you think this is the reason, or the movements of the market are normal ?
Bitcoin and others cryptocurrencies are at a bearish market and buying power is very low. The demand for investment into cryptocurrencies is reducing and that is why the price is down also. Bitcoin is going to recover in future and during bearish market the best thing to do is buying as you can get bitcoin cheap those times.
