Holding bitcoin is not the same thing as trading bitcoin. Gambling and trading are not the same thing too. Trading require you to learn trading skills but gambling require just some strategies. Trading can be risky like gambling, but they are not the same thing. If the price of bitcoin fall already, you can invest for months or years and you will most likely gain.
Totally agree with you holding is not considered as a gambling, tho people who blind entering market withour proper knowledge and only basic by luck and trade futures is a gambling hahahha
for you OP
Hahaha, Life is self actually gambling mate
full of risk and we want hope of a desired result. Just like you said and also life basically a game that involves money. 
But seriously if you consider crypto is gambling that stock and other investment platform is another gambling right?
