USDT is incorporated, can be frozen and not 100% supported with genuine USD fiat, so it will be more risky to hold instead of USD. Despite the fact that it's on top 3 market cap and has numerous holders, however the two of them aren't assurances to say it's protected.
It is like using dollars itself because it can be tracked and frozen if they think you are wrong or anything suspicious is found. I am not indulged in any illegal means but this control over cryptocurrencies and addresses kills the purpose for which bitcoin was made.
I just hodl a banch of usdt because i know that every exchange support it
Doesn't make any sense at all to me about holding a stable coin because the value is going to remain the same and what benefits are you going to get by holding it for years I can't really guess. Are you staking them and earning interest? If that's the case it makes proper sense but otherwise its quite perplexing.
The cost is extremely unpredictable right now, so it's smarter to purchase more modest sums throughout a more drawn out timeframe than to simply purchase at the same time. I think USDT keep stable and have potential greater cost depend how world circumstance, perhaps when get uplifting news usdt can get sway more exorbitant cost albeit few percent however more strength to keep stable on more exorbitant cost.
No matter how bullish the market gets, the value of the stable coin is going to remain the same in case you are expecting any kind of price changes in stable coins.
Yes if the dollar itself does well like your country's currency goes down in terms of USD then you will benefit because you get more fiat for the same USDT you hold. That's the only positive I can think of holding USDT.
