Guys, Can I export my coinomi zec nmc private keys n import/sweep into the respective core wallets, if so any issue or diferente procedure I should be aware? Another question, Is there any security benefit of using coinomi totally offline, n when I want to spend from one address I could sweep it into a new coinomi wallet? Is it safe too? Any benefit trying to protect a kind offline coinomi wallet? Releasing/sweeping one private into a new coinomi online wallet would compromise my "cold storage" of all other coins? Thanks, Rick
