Most centralised cryptocurrencies

When bitcoin was created, its primary purpose was to be decentralised. But several years later, we find among ourselves some of the centralised cryptocurrencies making it big. I thought I should apprise the traders of them so here's the list

1. Tether (USDT)
Tether is not only a centralised currency but also a big scam. I can write a book on why it is a scam but to keep it short,
Well basically it maintains the USD 1 value by collective belief of the masses that it is crypto USD . So they always buy it with Bitcoin at the USD-btc price. Now the problem is they can create tethers out of thin air (and they've been doing so).

This is very dangerous for the crypto world if it gets bigger.
They claim every tether is backed by USD but they also claim

There is no contractual right or other right or legal claim against us to redeem or exchange your Tethers for money. We do not guarantee any right of redemption or exchange of Tethers by us for money. There is no guarantee against losses when you buy, trade, sell, or redeem Tethers.

So I would recommend you guys to stay away from usdt as much as possible. Sooner than later, it is going to come crashing down

2. Ripple (XRP)
Ripple is technically not a scam but it isn't anything revolutionary either. Imagine if visa decided to call itself cryptocurrency and got ranked #1 on coinmarketcap. That's what ripple is. It is just grumpy old bankers trying to take back currency transactions from bitcoin. There is nothing decentralised about it. It is an oligarchic currency run by the big banks around the world

3. Waves (waves)
I love waves' sleek design,easy to use UI, dPOS system, the leasing system where balance still shows in your wallet. But despite all that, it is a centralised currency and platform. The concept of reissuablity makes it very much centralised. Other than that, the validity of currencies such as wUSD and wBTC depends on how long the devs decide to stay dedicated. Once they abandon the project, those tokens will be worthless.
But waves still has a long way to go and the devs seem to be dedicated into it. So it is fine to hold it. Just be careful

That's it for today folks, I was looking for more currencies to add to the list. If you know any, please post in the comment section
