I lock-in my first round of profits on SHIB at a 10x couple days ago. Stylishly i've learned how important and secured it is to have one's portfolio diversified into many quality coins since coming aboard.
Even when most altcoins are crashing, a few of the quality ones can give huge gains. I'm compounding my gains by rolling profits into unpumped coins at a cheaper rate. I don't care how many percentage will be added by year end, I just want to live for tomorrow first as many opportunities are under way.
Disregarding the status of SHIBA INU based on my view, it's good that you are doing such things to somehow secure profits even there's an anticipation that there might be another round of price increase that will happen in the future as a speculation. While doing that, you are gaining experience and that will help you to decide properly in the future.
Just continue with your strategy and see the result for yourself. Eventually, you can now automatically create a strategy based on a given situation.
