Thanks for that, it helped me a lot!

I spent the last couple of days playing around with the derivation paths to try and understand them better.
I was having trouble importing my mycelium wallet because i had many accounts, not just one.
So i found the bip32 derivation paths for the different accounts you have in your mycelium wallet are these:

(This is provided you have restored your Coinomi wallet using the same 12 words from your Mycelium Wallet).

Your first account is account #0, so:

Account 0 is at Derivation Path M/44H/0H/0H
Account 1 is at Derivation Path M/44H/0H/1H
Account 2 is at Derivation Path M/44H/0H/2H
Account 3 is at Derivation Path M/44H/0H/3H and so on...

The logic here is :
M/44H (purpose)
/0H (type of coin 0=BTC & 145=BCH)
/3H (Account#3).

Hope it helps those who try to import their BCH from Mycelium and they cannot see their funds because they have or had multiple accounts!

By the way, it's also possible to use those same derivation paths to access the BTC in your various Mycelium accounts, you just add a new BTC coin with that path in the advanced settings.

This is not a sweep, you access your funds directly like if you where using the Mycelium wallet!
