Is archain wallet good? Or are there better free wallets?
I am just now hearing about these archain wallet,but already quoted that it is not a bitcoin wallet so if OP lookinf for a bitcoin wallet the I will say that all the wallets other than hardware wallets are free,you can choose the wallets based on your usages.There are hot wallets,paper wallet,software wallets and hardware wallets are available.
If you are looking to store small amount of bitcoin the blockchain wallet is a good option and it have 2FA security also.But the wallets with private keys are more safer,so if you want one of these then Electrum is a best option.
