Today $10k might seem expensive to certain people, where tomorrow it might turn out to have been an absolute steal -- that's the nature of this market. I remember how I back in the days kept accumulating coins every week and month till the price reached $500. It's not that I didn't believe in the market anymore, but just the fact that for me personally, I had accumulated a decent number of coins already, so from that point I decided to just stick to holding. It perfectly demonstrates the different phases we have gone through in the last years, and will still go through, because I strongly believe that even at peak levels of nearly $20k, we still haven't seen even 10% of Bitcoin's ultimate potential price.
