For me Bitcoin has been my 100% portfolio and up to this point, I am glad that I choose that part even though Bitcoin price has undergone a lot of changes lately, my BTC vs $ balance has shown green and also red-negative movements which is a pointer to the activeness of bitcoin volatilities.
Knowing that Bitcoin is volatile in DCA pricing and also having a balanced market that shows not too much of a sign, e.g. 50% price movement within a few hours which is a sign of pump, or a drop in price significantly below 50% which is a sign of dumped.
Bitcoin has a cycle to help calculate its movement unlike those altcoins that have high centralization, subject to pump.
Good, in my case, it's like 90%+ on my portfolio. I just have 1 or 2 altcoins that I have invested for this year (no meme coins or shit coins for me). And I guess I have been long enough in this market that I'm no longer affected by the volatility. I just continue to buy whichever way I can, and just HODL.
For the majority if might be the case or not. Specially for newbies because it's really difficult to do that, buying in years and just day by day grind or weeks or months and seeing your portfolio growing when the price goes up, and then in this bear market, sideways this month alone.
