Earlier quoted context omitted.
Well it's actually a pretty bad transactional currency because it costs so much to transfer btc. So it's kinda the opposite, where people mostly hold it instead of transacting. The argument for a store of value is that of gold but easier to store and transfer, better security etc.. Whether it's a good one is for you to judge.
"costs so much to transfer btc" That's not true. The typical credit card processing fee ranges from about 1.3% to 3.5%. Average international remittance fees are about 7%. For comparison the average Bitcoin fee is about $1 right now, so 1% on a $100 transaction. So Bitcoin compares favorably to its competitors.
2) why did you pick $100 as your basis? If I try to buy a $5 sandwich in Bitcoin and have to pay 20% transaction fee that is not a good platform for transactions.
I like some parts of crypto, but transaction fees on most coins right now are not one of those parts.
