I would say it kind of depends on how long you are planning to hold on to your
BTC (
asset). I mean if you are planning to sell in 10 years, I agree it is trading in some extent. However at the same time, can you call something "trading" that involves a single trade in 10 years?

I think holding is simply an investment in an asset or stock with the hope that it's price will go up. wait..which then makes
BTC a "company" where we are the shareholders.

This is what exactly I meant, I should have posted this in a better sentences so that people could get what I exactly meant. Most people do think that buying now and keeping it , hoping it to goes up by $10 next month/year and sell it is consider as trading but the fact that it is not, it is more to like putting investment in
BTCselling and buying can also be called an investment, a short term investment, actually they belong to the same class, one is fast the other is slow
Actually selling and buying activity doesnt count as investment but is a trading activity. Investment is more or less into keeping things for long period of time hoping that the value of it could be better by the time . While trading is somehow different, most people that hold
BTC doesnt even bother when the price is lower by 1 % of the value when they bought it and keep on hoping that the value will go uo in a few weeks ahead but as a trader this will bother you
