They are clearly the market leaders in terms of online btc wallet. What are the alternatives?
I think the blockchain is one of the best online wallet,but there are lots of online wallets are available but none of its are highly secure to store our funds.But coinbase could be a good altenative for blockchain.info wallet,but recently I found that blockchain wallet has less fee than the coinbase.
But none of the supporting segwit addresses yet,so the fee is more than we compare to the other software wallets.
But electrum is also available in android platform,one of the best wallet for bitcoin,so you can try it also.
