3. Do you use free accelerator to save money on mining fee?
Some newbies I am sure, probably do use it as they think it makes their transaction go through quicker, although I don't think the accelerators are a suitable replacement to paying a higher transaction fee. I'll go through why below.
The 2 current transaction accelerators that i am 99% sure these newbies are using are the following.
Viabtc's transaction acclerator and
Antpool's acclerator Why these can't replace using a higher fee are the following reasons -
For Viabtc, it only accepts submissions every hour, and being a user of it, the 100 submissions are all done within every first minute of every hour. If you can consistently push through a transaction on the first min of every hour, then sure, cheap out on fees.
For antpool, that is an unlimited transaction accelerator, but the people paying higher fees will have their transaction included in the block first, so that's a no-no for the people with low fees.
Basically, if you send with medium fees and use antpool, should confirm it with next antpool block, no matter what fee you use and acclerate it with viabt, it'll confirm when viabtc mines a block.
Chipmixer looking to cheap out on fees and then use acclerators?
