Yeah! I have one big regret when it comes to Bitcoin. I joined the bandwagon in 2012. During that time, even faucets used to give a good amounts of Satoshi for every action. Also signature campaigns used to pay huge amounts of Bitcoins as per today's value. So I was able to save up a decent amount.
But I had sold most of them in 2017 when I had purchased my first apartment to fulfill the co-pay requirement. As per today's value, it is more than my total mortgage.
I wish I could have kept my Bitcoins intact.
The apartment you acquired with Bitcoin is actually a very good achievement. Although you may have spent significantly more Bitcoin than in 2017, acquiring an apartment that year is certainly a significant achievement.
I understand there's some regret, but we can't regret our achievements. While we may feel we moved too quickly, the need for housing is crucial. I think the steps you took in 2017 were excellent. Ultimately, you benefited from your Bitcoin savings before others did. I don't think that's worth regretting, as it's an achievement.
Furthermore, considering the total from 2017 to now, it's certainly been several years since you started collecting again, so there's no need to overly regret an achievement we've already achieved.
