You are absolutely right about the transaction fees, but I have a feeling that that is not a problem. There are many people that are applying the DCAing strategy, so anytime they want to accumulate Bitcoin, they can make use of the lighting network or accelerate the transaction so that it will be confirmed in just a matter of minutes (maybe 30 minutes).
There may be instances in which the lightning network might be helpful for both large transaction fees but lightning network surely has its own issues in regards to how much BTC can be held in such LN channels, and surely a lot of LN wallets are custodial rather than non-custodial, yet they could still serve as intermediary channels.
I am not sure how an accelerator resolves any kind of high fee problem, unless maybe you are referring to some of the free accelerators, which might not necessarily end up resolving issues of transactions getting stuck, and surely there are accelerators that charge extra, so that may well not end up resolving the issue of fees, even though it could help to resolve issues of transactions getting stuck.
However, I haven't used any of them, but with the kind of post and discussion at the technical board, I can tell that they are working perfectly. Although I am still planning to buy more coins next week with the help of the DCAing strategy, and if the transaction isn't confirmed quickly, then I will accelerate it.
Again, good luck using accelerators that may or may not lead you to success in getting your transaction to go through, but at least you can try it out and tell us if it is helping you in any kind of meaningful way.
Before I came across this post,
https://bitcointalk.org/index.php?topic=5034315.0 I was thinking of buying the same amount of Ethereum, then when it's confirmed, I will reconvert it back to BTC just because of the transaction, but now, I will not have to do so, I will just buy the BTC from p2p and accelerate it.
I was not following that thread, but it does look like there might be instances in which stuck transactions could be accelerated, yet I am still not sure how that resolves the amount of the transaction fee issue, except maybe if someone had transacted with too small of a fee, and the transaction is not going through then to get the assistance of some accelerator service, and wouldn't you need to pay if you were using such service regularly? But, yeah if you are transacting once every few months and then once in a while those transactions get stuck, there could be some use in terms of getting them unstuck and not necessarily having to pay any extra fee (if the accelerator really is "free.")
Ok. I finally looked through that "accelerator thread," and ultimately, it seems to me that there is no evidence that the OP of that accelerator thread has any connections to miners and/or abilities to speed up your BTC transaction, even though he is seeking tips for offering such services.
Hugeblack's post from last month is likely an accurate description of what is happening in that accelerator thread:
I don't see the logic of posting your transaction here. @OP's last activity was about two months ago. account has a negative trust regarding claims to accelerate transaction confirmations in order to get paid in tips, and there is no evidence that he can speed up transaction confirmation unless @OP has a connection to one of Mining pools or any data that confirms this to us, however, the service is paid.
It is better to stop publishing your transactions here because this will not help confirm them and will reduce your privacy. Use --->
