I want to create an website but i want to use the block.io api are they safe for 50+ BTC deposit or not? I mean if i held 50 BTC in my block.io wallet.
Any chance they will scam me? Did anyone used block.io before?
What kind of website you want to create? Because the only type of service I imagine is gambling site.
And if that is the case here why don't you use MoneyPot to help you fund your bankroll.
The only online wallet I would consider 'fine' is blockchain.info and they are still not ideal.
