More volatility means more opportunities to trade.
Yes, you can still make decent money when trading the volatility of bitcoin, but it is not a safe and recommended approach if compared to DCA. I see day to day trading with high volatility as gambling. But when it comes to DCA its totally different. The risk is less and yes you might be accumulating Bitcoin slowly, but you will surely meet your target. The special benefit of Dcaing in Bitcoin is that if you buy and hold,
you are pretty much guaranteed to make lots of money in the long term. There are no guarantees in bitcoin. Even if you use the term "pretty much" that is too high of expectations to be acting like you are guaranteed to profit, which is not true.
Bitcoin is an asymmetric bet to the upside, so you have good chances to be able to increase the amount that you invested by more than the amount that you invested.. while at the same time, it is not guaranteed to go up... but if you lose, you will only lose the amount that you invested.. so it surely should be a good reason to invest into bitcoin knowing that it could go either way, but if it goes down, you are ONLY going to lose the amount that you invested... so be careful not to invest more than you are willing to lose.
