More than a bit OT now... but the PayPal no-fee-for person-to-person brings to mind the only other alternative for that eg. Western Union. Again - fee.
No matter what, by design
BTC Tx fees MUST go up to finance operations be it Mega Farms, us smaller farms/miners and along with us - Pools.. Bigger problem with that is, the Powers That Be must get off their duffs and soon decide on how to make bigger blocks to handle the increased volume of transactions! Even with folks paying more the chain is still pretty backed up...
I recommend the Ledger wallets. Not sure what voodoo they do, but if you set the fee to "highest" level, which is their default, you will not pay a crazy amount and transaction will go through on the next block.
I've looked at them in the past. Just am not comfortable with having to rely on a physical device that will (someday) fail.
edit: Oh, re: coin mixers.
Whyy does the Media and so many folks think BTC Tx's are 'secure'? It's an open Public Ledger fer chrissake.
In early 2015 at the end of the AMT/Bitmine.ch A1 miner mess (at least my involvement with it), Opium2 and I brought up the matter of tracking BTC movements to/from AMT/ it's owner Joshua Zipkin, with a Dr. of CompSci friend of ours. Being intrigued with blockchain uses, he bit. I gave him VPN access to my RenderBeast (I dabble in 3D art) - which for then was 2nd from the top 6-core i7 ($1,800 for the CPU!) loaded with 128GB of insanely fast memory and a 1TB SSD array. Damn fine AMD GPU as well which today is prolly around $100 or less. At the time I got it - ouch...
He set up a local Full Bitcoin Node on it and within 2 weeks had written a tracer that takes any wallet address(s) as inputs, searches the entire chain at a rate of >50k Tx/Sec and reports all instances of and paths the coins took. In the process, since he was using Haskell he found some of their blockchain-specific search functions to be - lacking. Wrote streamlined versions that were Pushed and are now there for all. to use. One interesting find was early on several large BTC transfers
from Josh (AMT) to a known KnC wallet later followed a very steady 2x per-week 10
BTC income
to Josh's wallet from a KnC farm that was probably running A1 rigs that were kept from the screaming Public customers of Bitmine.ch (and AMT). Strangest part about that is that KnC and Bitmine.ch were supposed competitors so wtf? ...
