I would like to highlight most important crypto lesson of 2021 that is patience because I have missed out of coins like Shibu when I sold it for little profit or dump and it pumped 40x after I sold it, I would suggest you not to lose hope because those who have bought at peak in the past had to wait for years and they got good returns in 2021. No-one can predict crypto hence we cannot trust anyone including youtubers.
You missed nothing unless you made zero profits, if you sold your shiba inu very early it's because you already doubled your money, it's a smart move honestly because ask yourself this question, how many projects have became so good as shiba inu in the past months till date? Many meme coins tried to but no one was as good as shiba
