Hey
I once came across a time when I was unsure where the market is going to take us , thus I brought at a very high price , unfortunately the price came down as quickly as it climbed up.
The reason I believe I haven't lost even a single penny is because
I believe you cannot loose when you don't encash.Therefore I still believe holding for the long term can actually help you .
This has been my personal experience and i have lost a lot. It may still be true that you wont lose a single penny if you dont cash out the money you own as an digital asset BUT HODLing too much might have a bad effect. The prices may change drastically and the value you are keeping might fall to nothing. HODLing might still be useful but you need a lot of patience and keep supporting the Cryptocurrency that you are rooting for.
