Most of the bad review seem to be from people who don't know how bitcoin works.
For example, one gave 1 star commenting with
..this wallet says transaction will go through within 10 minutes, but it took 60+... there are online service delivering much more quality..
Other people complained about the not working feature, connecting mycelium with trezor.
Im using mycelium myself. I think thats one of the best mobile wallets available for android.
I don't see any option that you can pay 1 sat/byte where honestly you see this option?
Under "low prio" i have the option to choose between 0, 10 and 21 sat/byte fee.
Yep. You can't really trust or rely on those reviews. Some of those reviews are quiet dumb. Despite of all of this, I still continue using Mycelium.
I think its just competitors strategy they are just taking down mycelium i personally use mycelium for a month ago and until now its fine also updated my mycelium to new version which is you can slide how much fee you wanted to pay.. unlike before you can only choose fixed fee normal priorty economic or slow..
Right now with new version i think you can choose ever 1 sat per byte.. but still not tested yet..
Maybe those who are commented are who experience in their wallet that i think the problem about there android phone is the version or low end phone this is i think the main problem about reviewers who use mycelium..
