Until now, many investors or holders are using it, and I am included, and the number of communities that will use this DCA will increase in the coming
days or time.
Perhaps bitcoin is the only cryptocurrency that the dollar cost averaging has been proven to be the best method to acquire with because other cryptocurrencies are not as expensive as bitcoin only Ethereum is second to bitcoin in price hence acquire other cryptocurrencies might not need to be DCAed as it's cheap one can buy them at any given time.
Investors are without doubt that Bitcoin will be around for quite a longer period, which isn't a property that shitcoins share with Bitcoin. Shitcoins can disappear any time and anyday, along with investors' funds and this possibility has made investors develop that doubt in them, and even those who go into it, are only there for the short-term gains, and since they're not there for the long-term and DCA as we know is a long-term approach, no one would consider applying the technique when investing in altcoins.
