Let's discuss the potential effects of stable coins which are bound to usd or eur. We usually use them to avoid the volatility or short bitcoin in a way. There are many stable coins in the last year. By writing threat, I didn't mean issues like tether's issue. I mean, they are not coins, they are just usd and eur.
Stable coins have zero threat to the bitcoins. Coin is stable only if is artificially controlled by a central body and hence stable coins are centralized ones. You should not compare the centralized coins with decentralized ones. Tether has already big issues associated with it and i do not understand why people still keep their money in tether.
Well, actually, I wasn't mentioning tether is an issue but for Bitcoin, it is a threat and we have seen it. We may have new tether examples in the future with other stable coins. This is another part of the threat.
