Hi guys, what are stable coins exactly?
Isn't the name self explanatory?
STABLE coins, which price is stable.
Are they a good way to look in profits from the volatility of the crypto market?
Obviously. The same way you can buy and sell BTC for USD, you can use them as a way to avoid losing money while the price is dropping.
How do you transfer your money out of the altcoin and into a stable coin?
By trading your coins for them in an exchange.
Are they any stable coins which do not require intrusive KYC details?
All of them? AFAIK you don't actually need do to any KYC verification to trade them in specific. E.g: right now, you can trade any coin for USDT at Binance without doing any KYC.
Do you think stable coins are the future?
What do you mean "the future"? They will be used in the market, but not as the main currency.
Stable coin now only USDT/TETHER, ~snip~
Not only USDT. There is DAI and TrueUSD as the second ones most known and a few others like bitUSD/bitEUR and Nubits.
