Although you made a valid point, but some people may not be encouraged to invest by the way you presented it. There are two ways to invest in Bitcoin, long-term and short-term. This is because not everyone has the patience to wait and hold Bitcoin for a long time, and since Bitcoin is designed to be used by everyone, that's why they made it investment optional for users. Both options long-term and short-term are profitable, but the long-term investments are more profitable than the short-term investment. If you decide to stick with short-term investments, there is nothing wrong with that.
Usually short-term with BTC ends up bad for people that cannot see hodl as a viable option - however, sure, one may try to get something out of BTC in a short-term, however, it's not a stable option, imo.
