5000NAHMII (75USD) GIVEAWAY for the one who can help me out tranasferring some nahmi from second layer to firstlayer ?

1) The thing is that im trying to sent some of my Nahmii coins to Ethereum first layer in my metamask account and from there use uniswap to swap them to other coins so that i can cash out some of it. I did access my hubii core and can see my Nahmii coins on the second layer. Just to test it out i tried to sent a small amount Nahmii to my metamask ether account but its not visible there ?
I dont know if im doing something wrong ?
But i read that to cash out i need to transfer them from second layer to first layer ethereum and then use Uniswap ? and im not sure how to do this other than what i tried above.?

Anyone who can help out on this ?   

1)Do you know how to transfer your nahmii from second layer to firstlayer, so that they are visible on my metamask ?

2)Do you know if Hubii coins will continue to give airdrops of nahmii coins ?
