Please give me a suggestion to choose a WAVES and BITCOIN wallet that you think is safe .. Thank you in advance for all your participation ..
I recommend binance.
Binance is a Hong Kong-based crypto exchange launched by developer Changpeng Zhao in July 2017. Zhao Beijie Technology Company created the exchange after its successful ICO managed to raise as much as $ 15 million.
Beijie Technology and its founders maintain an impressive track record in the industry. CV Zhao achieved a high profile position, such as technical director at Blockchain.info, and his company now provides a trading system that has more than 30 other platforms.
Wait what?? Seriously Binance is a centralized exchange and storing your bitcoin out there is a bad idea, please don't recommend someone to use exchange or something that they can't control the private key.
