HODLING bitcoin over time has proven to be the only strategy that works out 100% of the time....eventually.
Look at the price journey since the 1st block was mined & youll see the price always rises to reach a new ATH....eventually.
Seriously if you can wait a few years & have patience youll be handsomely rewarded.
I sorry to disagree but HODL is not 100% working because the truth is holding is a very tough decision to make. Like when i bought my Bitcoin at the price of $19,500 and then slowly it fall down to $8,000 in which later after that i realize the huge lose after of my constant holding so therefore how can we measure a 100% HODL success on this situation? The truth is HODL is very tough because the market is really unpredictable that is why it was classified as risky investment.
