No.
- How comfortable are you every time you transfer to a remote address?
Pretty comfortable. It wasn't like that at the beginning though, I was very stressed when I was sending bigger amounts but after some time you get used to the fact that its non reversible.
- Would you be more comfortable using a helper?
Not really, never really thought about wanting to have something like that as I got used to the current system where you are responsible for your own money and no bank or other 3rd can rectify your mistake.
- What do you use today to mitigate this risk?
I check first and last 4-5 characters when I am sending smaller amounts but when I am sending bigger ones I usually check the whole address.
