Brother, You are absolutely right that crypto market is extremely volatile & heavily manipulated, the reason behind it is, its maketcap, which is much lower compared to Stocks and Commodities markets but more or less all markets are manipulated, there is no exception. I have seen Dow jones and S &P 500 indexes of US market crashing more than 10% in a single day even Gold market crashes when oversold. Another example is Pakistan stock exchange which sheds more than 2000 points of its index in a single session. The question arises " How do you protect your funds when market crashes. The only solution is, Always use stop loss to save your capital.
