Recently my trading strategies that I bought bitcoin when bitcoin price more than $40000 and holding but recently market crashing, it already lost more than a $670 dollars. It's my biggest lost because I sold all my cryptocurrencies and converted into Bitcoin. Now I am waiting for roadmap to $40k again...
It don't have to be a loss, you just have to hold and sooner or later those losses you see will turn to gains. You only lose when you sell and your decision of turning all your portfolio to bitcoin isn't a bad one.
We'll soon enter the bear market probably by year ending or early next year do securing yourself in the safest cryptocurrency out in the market is the best decision you could market after trading to stablecoin.
But since it won't be quite easy to spot the bottom to sell then converting to bitcoin is also ok as it offers you the opportunity to also partake in future price increase of the market and an assurance of making profit after the storm.
