Never say never. From what I've seen so far, it seems that Shiba has great potential to blow up. Despite the fact that its price is down at the moment I believe it can surpass its 2021 ATH when another rally sets in this year. BTW, it won't be a bad idea for you to throw a few dollar on it now and wait a few months to reap great ROI. As for regret of 2021, I can't finger any. Rather I had a change in business mindset and explored more opportunities.
