Billing questions

Will it ever be possible to put money on the account to have "credit?" I'd like to raise money and dump it all into covering hosting for when the bill starts getting out of hand. Which of course implies success for my project. Is credit card the only payment method that there will be? Can there be more? Paypal? Crypto? I just need the ability for people to contribute to hosting of my project more directly than sending money to me and me using a CC.

I hope my question is clear, sorry if I rambled.
