Is it true that a friend recommended me to buy digital currency for transaction on SunCoin platform and only need to pay a deposit to operate? Because this is my first contact
Well, SunCoin doesn't look and sound like a legit marketplace to invest your $10,000 in digital currency.
There are many highly reputable platforms to invest your $10,000 in digital currency such as Binance, Poloniex, BitMex, Kraken, and Bittrex.
Thats a big money for me and I will never listen easily to any suggestion especially the exchange that I didnt know. If the OP wants a safe place then he must consider this suggestion. If you are living in a place where crypto is ok then look for some good exchange there and do your research. Big money should be invested carefully, dont rush in the market.
