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.
The most important thing that you need to apply for yourself is risk management. No matter if it's a shitcoin, a pump and dump coin, or a long term coin, just invest an amount that you can afford to lose or treating it as "dead money".
It's good that you've made some nice profit with SHIB despite that it doesn't have real fundamentals or use cases. Just manage your risks very well and remain financially stable. You'll be fine with that mindset.
