Although that altcoins aren't going anywhere, Bitcoin is still the crypto that I am most confident in investing and trading. It is the most popular right now and widely adopted and accepted by most countries whether they are pro or in the grey area like El Salvador, Central African Republic, The Philippines, etc. It has the most trading volume and unbeatable market capitalization and was recognized by most governments, financial institutions, traditional companies, etc. This is why I am doing DCA with Bitcoin regardless of the bear market situation today.
