Whats the best apps for buying and sending bitcoin instantly?

I really like Strike, but the limits are terrible.

Coinbase imposes a 17-day hold when using ACH before you can transfer Bitcoin out.

Which exchanges let you send Bitcoin to external wallets right away?

The BitPay app or website lets you buy Bitcoin in a snap! Just choose how much you want, and tell them where to send your new Bitcoin. Easy!

Bitcoinwell App i have personally used it and worked well for me and i recommend it to you Zachary. You can directly deposit to your cold wallet. Its the cheapest option with the lowest fees.
