for what its worth you recently changed ur prices, but vn at your now higher prices its not like a person pays500ksat and get 500ksat channel, they get 1mill sat channel
for what its worth, by opening a channel before even having a blockchain locked and confirmed tx peg is a risk
for what its worth, for LN to even allow channels to open without a pegged tx is a risk (opening a msat balance but collateral being coinbase.com data) as this shows its possible in code/technically to open channels without needing a blockchain tether AKA fractional reserving
1. We actually lowered prices on the capacity-only Thor channels (non-Turbo), we never raised them afaik. I'm not sure what you mean.
2. You misunderstand how Turbo channels work. The risk is Bitrefill's because we are fronting the BTC in that channel
3. There is no concept of what LN "allows". Channel rules are established between the two parties that enter them, it is voluntary. That means you can agree to any rules you want. If you use rules that are different than other LN wallets or the rest of the network, you will be limited to a subnetwork of people using the same rules. Turbo channel opening requires a custom channel, but there is nothing fractional about it. It still requires unencumbered BTC to allocate the balance. It's just that Bitrefill choose to "give" our BTC instantly to you with Turbo because you have already made a separate payment to us of sufficient amount. This same concept can be used to create larger channels than the common protocol too. If we wanted, we could open a channel right now with 10BTC in it, it would just require updating the software we use to be compatible with each other.
Don't confuse Lightning protocol with Bitcoin protocol, Lightning is real peer-to-peer interacting and channels can have any rules on top of BTC as an anchor. Nothing fractional, and nothing custodial about a Turbo channel.
