The main implication is that the price of bitcoin will go up and down, so if we convert it to stablecoin before DCAing then our risk would be lower because we can buy more coins when they're cheaper than usual.
What I am yet to understand is why sell off to stablecoin and then start DCAing back into bitcoin again. The only reason why one will be doing this is when the asset isn’t the one you are going to DCA into. For example if you’re planning to sell off your bitcoin now all in the name of there is a possible chance of it dipping below again and if you sell now that it is high you can get a discount or add up quantities when you buy later, i wouldn’t say this is a bad idea but it certainly not the best form of idea in a consolidating or a fluctuating market like this.
You might sell off today and probably the market bounce back tomorrow and that means you’re already in a loss, this particular market condition isn’t favourable for selling and buying back, rather it is a period of holding and accumulating more if you have means. This means that if you already have some bitcoin holdings, hold them and do not panic and sell, the market will most certainly bounce back.
And if you’re looking for extra accumulation then you can simply daily DCA now if you have extra funds because the market is in a consolidating stage now and good grant more opportunity to accumulate more
