Bitcoin goes down $4000 . What is happening 😳

I entered the crypto market in late December last year, a few weeks before we reached Bitcoin's ATH. Needless to say no matter what I bought, I'm down loads, mostly because of when I bought in.
I have to say that through all the dips and crashes, I never really became too scared or worried. However, seeing that I'm now down over 95% of my original investment, I can honestly say I am a bit worried. I invested $12,000 USD over the course of a few months and my portfolio now is worth less than $800. I am a firm believer in what I invested in, and I know that the technology hasn't changed. I know that I haven't lost anything until I've sold. But it's hard not to feel almost robbed while looking at my portfolios current value.
My portfolio currently consists of ADA, ETH, TRX, NCASH, BCPT, and WABI. I'm not a day trader and I've been wondering if it might be a better idea to zero in on two-three-or-four of these projects with the best chance of rebounding stronger instead of leaving it as is.
Anyway, I hope you guys are all doing well. There's more to life than crypto. I'm thankful to say I only invested what I could afford to lose, but that $6k definitely wouldve been nice to put towards other things. I might be worried at the moment, but I definitely havent lost faith.
