My method to not loosing during bear market

As everyone can see we have entered a downtrend in cryptocurrency market. But we can see a classic pattern, when everything goes down fast then it start to recover at some point. My method is to not just hold the tokens just sell them when u feel it is starting to going down and buy when it start to go up. This downtrend will last to 1st of August atleast. This way by every transaction you will have the same value but more tokens. It is pretty logical but nobody will tell that because such movements cause bigger instability in the market people advice you to dont touch your portfolio because more people will do this the bigger drops will happen. They say BUY and HODL or just HODL and they do something different they just short trade.
