Hello. A good place to start reading up is this site; https://vechaininsider.com/guides/guide-to-vechain-nodes-and-node-rewards/ . People typically buy/sell Xnodes on the trading markets as Xnodes cant be obtained now besides from the trading market.
I would say the comparison is that VeChain altogether has a broader spectrum of marketability and concepts to a variety of different markets spanning across the Globe 🌍 Strategic Partnerships are key just not regular partnerships just because IBM has Walmart doesn’t mean much because Walmart themselves have a competitive themselves
X node markets would have happened either way, VeChain just took the initiatve to make a trusted one before scams took advantage of people. It's the Safe Haven solution for pooling VET nodes all over again. Would have happened either way, but now people won't get scammed by bad actors
Unfortunately this is the cycle of markets, this has and will continue to happen depending on the fundamentals of all markets (especially because digital marketplace is becoming so widespread, with ease of access for novice traders), so this will indeed happen again, and again.. and again.
Cryptocurrencies will be based on a blockchain, but not everything that exists on a blockchain is made to be a currency (in the same way we might think of bitcoin or lite coin). Through various cross-chain technology and exchange markets however, it is easy to exchange one token for another.
