I gonna try coinkite, any opinions on it? good, bad?
Coinkite features:
Money controlled by a third party
Centralized validation
Remote app
Vulnerable environment
Basic privacyhttps://bitcoin.org/en/choose-your-walletBetter to use Bitgo or GA for web wallet. And you should store your coins on cold wallet, electrum is my recommendation.
on my side i use coinbase with 2fa security,the other is blockchain for fast transaction. if you want to stuck your bitcoin to many moths or days you use bitcoin core the most popular and secured wallet...
2FA security makes the account safer from unauthorized activity.
I use it too, at the moment it seems good and their referral system is high too.
But the whole system(coinbase) does not provide private key for the funds there.
Their reff commision is depends on country.
And yes they is just an exchanger which also web wallet, they will not give you a private key.
