Sure, you might snag a few wins, but in the long run, you WILL get rekt.
Bitcoin is an unstoppable train. If you don't believe in its power, don't hop on.
But here's the golden rule: Never bet against Bitcoin.
Many people will disagree with you because in this market, there are two sides of movements, up and down. There are different times when market will have liquidations on either up or down way, with Short squeeze or Long squeeze respectively.
It's not rare to see both Long and Short squeezes within couple of minutes in this volatile market.
The bottom line is not bet against Bitcoin, I see you meant don't short against Bitcoin, but "Don't use leverage in Bitcoin market, for either Long or Short positions".
Liquidation data
https://www.coinglass.com/LiquidationDatathe short squeeze and long squeeze isn't really a problem when we don't over leverage and set tolerance against these kind of things, all the price swing so far that I've seen never ever liquidate people with leverage below 3x beyond that its exposed to the short or long squeeze but if we're talking about don't bet against bitcoin it does make sense, the fact that bitcoin keep increase its all time high means people that shorted bitcoin are just making temporary profit amidst the chaos like the sudden price pullback but will eventually caught up with the price pump and being margin called eventually if they keep shorting against bitcoin, they are not playing the long term game, they just playing the short game and will sees mediocre profit from their shorting activities.
longing bitcoin is what makes people rich these days, the people that longed bitcoin from the day of bearish probably making a ton, the people that don't over leverage are rather spared against the long squeeze and they can have peace of mind.
so shorting bitcoin is not a great strategy for long term. well it never was.
