Is there any alternative to cashing out and paying enormous taxes? It makes no sense to swap 100k worth of BTC to an altcoin when we expect a BTC crash of 40%, when all other altcoins are likely to crash even harder.
I wish there was something that behaved conversely to the BTC price.
I do not think that there are many that will go up when bitcoin goes down, most of them will go down with bitcoin, only one that is standing and not going up or down is the stablecoins and that is why they are being purchased when the market is bear, most people move to getting to that point and we can't really consider that changing that much.
Just focus on getting a good result whenever you can during bull run and when it's bear run either keep DCA your way into cheaper entry point to make more money or you could just end up doing more when the time comes and you could just focus on making money from stablecoins and standing still and re-enter when the price drops a lot. Those are your options when bitcoin goes down and most people use these two to make money when bear market comes.
