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.
