Hello everyone, greetings and respect, I have just implemented a bitcoin BTC payment system in my small community with cold wallets but not all of them are young with internet access. Many of them have expressed their concern to me. It all comes down to how can I transfer bitcoin payments to you without internet?
I do not know if this possibility had been discussed before in this wonderful forum. But I need your help to see if all together we can achieve this.
Hi ya,
Depends where you're at some places you maybe able to use SMS to bypass internet availability issues.
Wallet such as Machankura is one of them.
https://machankura.com/ for other locations I use
https://blockstream.info/tx/push or

as far as getting your full node sync'ed to full height, one cheap method would be to use blockchain streaming services, some of which is free, which can be found at
https://blockstream.com/satellite/#satellite_network-coverageYou can build your own satellite kit or keep your own node up and in sync like I did, but its effectiveness rely depend where you set sail. Generally speaking you need somewhere close to 2Kbyte/sec of download speed to maintain sync for an full node (for receive payment), but much lesser if you want to send payment (most likely around 200-300 bytes, less if done via PW2PKH)
