Which wallets is best that support ERC 20 and how do I sign in to seed wallet
MEW and off topic. help!! i stored my BTC in my ether wallet and i cant see it anywhere.
Ok, how did you do that? 
I use myetherwallet for me it suits me the most. I started using it ever since I began investing and involved in bitcoin. I find it easy and very user friendly and before trusting my coins with it I have read a lot of good reviews from it plus it has multiple security and ways before getting the information in your wallet which somehow give me peace of mind.
How do you exactly send bitcoin to ether address? I'm currently using cryptopia.co.nz ; amazing website,totally worth a try!
Cryptopia is exchange, it can be used to store bitcoins but it is not a wallet.
