Thanks everyone who is trying to help.

From the wallets you people mention I think I will try Blue Wallet. I have heard of Mycelium but never of Schildbach. That answers my question about bitcoin wallets.

For the tron and tether wallets. Unstoppable Wallet and atomicdex.io were mentioned. I have never used these. Sorry o_e_l_e_o. I would also not use tether if I dont have to. What can I do when people keep turning down my offers to use bitcoin? I will have no one to trade with unless I do what others do. Using Unstoppable Wallet or atomicdex.io for the swap seems ok. Anyone with some experience with these exchanges and wallets that can comment how good they work?
