I think the reason why many newbies delay investing in Bitcoin is because they wait for the perfect financial situation. They may think that the income will be high, the backup fund will be fully prepared, there will be no debt, the monthly expenses will be completely stable, and then they will think about starting Bitcoin accumulation . But people's lives may never be perfect. And there is no rule that you have to invest a very large amount from the first day when investing in Bitcoin. It is possible to regularly DCA in Bitcoin with a small amount according to discretionary income and cash flow.
This advise is for a person that is earning well and have money to spare for investment, as much as I will like to see everyone buy Bitcoin, I will like to see people in good condition. If you are not financially stable, go and fix your life before you want to buy Bitcoin. It you don't buy today you will be able to buy tomorrow. It's not like because you skip the market for the year you will not be able to buy this year, some people that didn't buy last year had it today and cheaper.
But yes, backup fund is important. So an investor who is building a backup fund should start working immediately after doing DCA. The bottom line is that responsible behavior often does not wait for perfect financial conditions. Being responsible does not mean waiting until everything is perfect. It is actually right to start small by understanding your capabilities and at the same time strengthen your financial system. You do not have to be rich to start your Bitcoin journey. However, you should keep in mind that you should not invest in Bitcoin in an over aggressively .
If you are earning enough money and you know that you are financially able to buy Bitcoin, even if you don't buy everything at once, you can buy it gradually with DCA, this makes more sense if you are balance and stable. If you are not financially stable, even if you use all the strategies in further mathematics to buy the coin, you will sell it when you are later financially pressure. Better be ready and stable than buy now and sell later at loss.
