All valid points and those are the only that I can think of that anyone can really ask for when choosing to use bitcoin in the first place.

Choose the investment primarily for the needs of each person, if a person does not have enough knowledge of that investment they will not be able to make a profit, with my needs I choose Bitcoin because I have found I know about Bitcoin and I have seen its good future
after I saw What problems with transactions and how much they cost, I think that Bitcoin can suffer very much and with it people who invest their money will suffer. To date, the best indicator is still the etherium and I prefer it. And I bypass the Bitcoin side for today.
