Will banks use ripple????

Ripple!!!!!!

It gives me nice profit I buy for 0.2 btc 48k ripple and sold before few days for 5.5 btc. So nice profit there.
But question is will banks use ripple???
I'm not expert how banks doing their job but peoples say it can cut costs of transactions. Do you trust that???

I do not. Banks have costs when transact money but to who they pay that costs??? I think one bank pay other bank so sometimes they have costs and sometimes make money on it. Do they need ripple. Of course they don't. Peoples say costs but who pay that costs??? We pay and for banks it's just profit.
And if all above wrong do you think banks would pay ripple billions of dollars or you think they would make their own solution for that?? Don't be crazy it's just pump and some peoples would take millions here and who will lose??
You. You would lose I don't trust them think about all this and decide is it worth to keep ripple
