If you want to know the advantages of decentralized exchanges, just take a look at the news about centralized exchanges being hacked from time to time and look what happens with their customers and their funds inside those exchanges. And this is not the only danger, a centralized exchange can shut down or just disappear with their customer's funds.

I don't know anything about this coin but for what I have read in the first post, I understand that they are not going to store all users keys there, but only the genesis private keys. Am I right?

In any case, tether can be a threat to tether holders. If those accusations against tether turn out to be true, any harm that it could cause on Bitcoin would be temporary, but for tether holders it would be devastating.

The question is not only if, but also what. Unless you think that all altcoins will pump you will need to guess and chose the ones that will do it in case that an altcoin season comes.

There is nothing strange in that graphic, the projects that are moving to binance chain are doing it for the hype, looking for a quick pump, but after the quick pump comes a quick dump and, at the end, the real value of the coin shows itself.

It depends, there have been some projects in the past that have been abandoned by their developers but the community have taken over and refloated them. In those cases, the coin can survive, otherwise, it can't.

This scam technique has existed since long before cryptocurrencies, I remember there was a virus disguised as a Paypal money generator that worked the same way as this malware. Hackers even created fake videos that they uploaded to Youtube with a link to download the virus. Over time, it's inevitable that all scam schemes are adapted to crypto. I guess sooner or later we will receive an email of a Nigerian prince asking us to send him one bitcoin or something like that.

The funny thing is that when Facebook launches their coin they will ensure people that it will be private and that transactions will be confidential. Anyway, anyone that will use their coin knows what they are doing.

That list is counting the value in dollars of those altcoins, it could be interesting to see a list that counted the value in BTC to see the real growth of those coins.

Taking into account that 99% of bitcoin forks fall into oblivion in a very short time due to the fact that those forks are useless coins and nobody is really interested in them, it's clear that the answer is no. In fact, it's strange that there still are forks showing up.

Reading the note posted by the OP it's not clear to me if what Facebook is going to launch is really a cryptocurrency or not, they don't say if this coin will have its own blockchain or if it will not have any blockchain at all, according to what is written there it seems Facebook is going to launch some kind of internal payment processor with an “in-game currency”.

Is it already possible to withdraw the BAT tokens to a personal wallet? Because until that is possible, this idea, although it is good and can be extended to Facebook, Instagram or LinkedIn users, will not have a big impact.

I don't like the idea of storing the keys in the cloud, even if they are encrypted, there is a risk of someone will hack your account, access your keys and find the way to decrypt them. About the idea of printing the key, I think it could be better to write it by hand on a paper instead of using the printer.

You are talking as if ICOs and IEOs were two absolutely different things when the second is an evolution of the first, the same with STOs, and I guess new models will keep on appearing in the future. What is true is that the IEO model is the most popular right now.

Assuming all the projects that have moved to Binance chain have taken that decision because of the hype, the question to make is, how much time will that hype last? What will happen to those projects after the hype is gone? Will there still be projects that move to Binance chain when this does not mean an immediate pump?

If they see a business opportunity in doing it, or if they see it as a way to attract customers or any other benefit, then it's possible that they will launch their own cryptocurrency, but they will do it only it that cryptocurrency has a purpose and they can benefit in any way.

There is not a specific model that guarantees bigger profits, it's not about the model but about the project. In addition to this, a little luck is needed regarding the moment when they launch their project, it's very important not to get caught by a big dump and a bear market.

And there will always be, scammers always find new ways, if you close a door, they open another one. The best measure is to educate people, teach them to be careful, the same way you teach them to be careful with phishing links they receive in their emails or through SMS.

It's hard to predict the exact year or the right moment when this will happen, but I also think Bitcoin, and maybe Ethereum, will become mainstream and widely used in the future. Regarding Ripple, I don't agree at all.

I'm afraid you are confusing a bull run with getting profit. A bull run is when the price rises massively during a long period of time, it has nothing to do with the price at which you bought a coin, it's something objective, not subjective. A different thing the profit you can get or not from it.
