I also started last year by buying bitcoin every week with the intention of never selling it again and having the confidence to hold it until old age or for my retirement. If you have more money, keep buying aggressively and if you don't have money, don't take out a loan to buy bitcoin. Invest casually without having to force yourself to continue buying aggressively but just focus on DCA.
Yes, I totally agree to this, their is no need of feeling regret over a spilt milk, it has already happened, now it's left for you to re-write your wrong so that you can have a better future, so making your past your Burden is really a wrong thing to do at this present day and time, when their are still countless opportunities out their in doing the right thing, by accumulating as much Bitcoin as possible, so as to be able to build a generational wealth on the longer run.
And talking about loan, it's really a wrong thing to do, because you are putting yourself understand unnecessary pressure that will warrant you to sell off your holdings, even though it's not your will, so that you are not going to defaulting on your loan repayment, so it's very important that you invest with your own personal money, and not just that, a money you can be able to do without for a very long period of time.
