I holded some fiat and tether, and I saw bottom few times and I buy, and price goes lower, and I buy again and it goes down again, with btc crash wasn't hard, but altcoins were bloodbath!
People quite often focus too much on
buy the dip while during bear markets it's not going to help you at all, and it seems that you are one of these people. Every dip in a bear market can become a lower high, never forget that.
I remember how I was smart buying BTX at 11$, I thought it cant go lower
That's a common rookie mistake. Altcoins in 99% of the cases don't serve a purpose at all, and that definitely applies to BTX. When buying these coins you should expect them to lose +90% of their value.
In other words, never blatantly assume that an altcoin won't go down further just because you think it's already low, because it can and likely will go down far lower. BTXs fundamental value is close to zero in my opinion.
These coins are meant to be used as a quick-flip, and not to hodl for a long period of time.
