If you ask me, it's more about use about 10% of monthly salary to DCA, then save the rest. Because if we are lucky, and a golden opportunity comes again - it might be a good time to be irresponsible and use up to 90% of your savings to buy the DIP.
Using 10% of monthly salary by salary earners is not a bad idea, I consider this one of the best approach when it comes to DCA, cause one would still have reserve funds as a leverage to take advantage of the market when their's a massive dip for instance about weeks ago when Bitcoin fell below $50k. This is the more reason why it's advised that people shouldn't loan money to go into Cryptocurrency, imagine if someone made entry with a loaned money at $60k plus and the market declined below $50k they'll end up being in a big mess cause I wonder how they'll pay off the debt, investing on Bitcoin especially when someone is using the DCA method is meant for those who got a stable income and not some jobless person trying to alleviate themselves with the little funds they got through Bitcoin.
Investing with 10% of our weekly or monthly salary is a bit small and a bit high depending on what is been received weekly or monthly, that is to say there are investors who's salary is very small to the extent that they barely sustain themselves till next salary and there are also investors who receive handsome salary that even if the salary is been divided into 3 parts, 1 part of it can be enough till the other month so this kind of investor 10% will be like a child's play. In summary the percentage to use for investment is dependent of the weekly or monthly salary.
Dude, lets be specific what we are talking or discussing here is not cryptocurrency rather what we are talking about is Bitcoin investment and going to loan money to do crypto is very risky and then again you are sounding like a trader because even you invest or made an entry when the price of Bitcoin was/is $60k plus and then the market declined to $50k that doesn't make investor to be in a mess unless you are trading I mean that's volatility it is band to happen and sooner or later it will take an uptrend.
