Sorry if this is already asked by some1,
as I rmb I heard of this before, but dunno is it just a scam...
is there any BTC wallet there will provide you interest?

You can Find Many Bitcoin Wallets That are Providing Interest On your Bitcoins But I Don't Trust that Type Of Bitcoin Wallets Because they Can Scam your when they got a Bigger Deposits From their Wallet Users....
I Also Suggest you to Don't Use that Type of Wallets Just Use Wallets Like Blockchain and Coinbase that are Safest to Store your Bitcoins....
