Have there been made any calculations how high the transaction fees for bitcoin main network could get in the future?
I currently have my BTC stored on a MultiSig cold wallet, which can't be connected to a lightning node. Do you think it's a better idea to move them to a lightning wallet like on electrum for example before the transaction fees get too high? I want to avoid paying a big amount just for one transaction in the main network
I am not sure what your purpose is but if you are a long-term holder then I am sure you do not need to worry about the temporary fee hikes. Moreover, it also depends on how much Bitcoin is getting transacted because if the volume is significantly large then whales definitely do not care about the charges required to transfer. It's also about the time. Once I had no rush and out of curiosity I just wanted to transfer my funds to the ledger. I broadcasted the transaction with low fees and it cleared my payment after 6-7 days. I think based on the scenario one can always make changes in the way we transact. This is a need of the future.
Because whenever the price goes up peeps start getting nervous about their sell orders and everyone at once starts broadcasting so it is obvious that we will have congestion in the network. This doesn't solve the problem permanently but yeah it can make things work during that temporary hikes.
