A question was posed to me by a family member if we should start DCA'ing into crypto as it becomes more readily accepted as a payment method

I am not a crypto investor and am not very knowledgable in the space. I have a small position in $COIN, but that was a FOMO/flyer position

My thoughts on crypto as a whole are that it seems more like an investment since the value appreciates over time (for the most part). The price appreciation does not make it a strong transactional token (thinking about the guy who bought pizza with Bitcoin). However, I do think there is the potential for crypto to eventually become a currency.

That being said, my response to the family member's question was - who will be the players in the crypto transaction space if/when these currencies become more accepted as a form of payment?

Will it be somebody like the traditional $V or $MA?

Is it a current crypto space player like $SQ, $PYPL or $COIN?

I think there could potentially be value in the transactional space.

Again, I have very minimal knowledge in crypto, but wanted to ask the question - what companies will be leaders in transactions as usage of crypto grows?
