I want to assume that there are few people, who make several profits from trading altcoins, but sell their profit to bitcoin, and then over time while holding bitcoin, it dumps and their profits dips alongside bitcoin.
Why not do it this way ?
Since you trade mostly in altcoins, as soon as your make your profits, sell them to stable coins or fiats, close that trade chapter.
If you are passionate about hodling bitcoin, always convert to usdt or other stable coins and be patient for a fair entry point. Because the market isn't running away
What do you think everyone ? is there a better pattern that can be practiced?
I am open to more suggestions.
Some traders are already doing this, they always find their way to make a way of saving their assets than losing it. But, there is no way to escape loss, even the strategy you suggested that was already been used by other traders is not enough to escape loss. There's still a percentage where you will lose in trading depends on the movement of the market.
