Hi, I am new to all this, but help me understand this. If there is a crypto coin that is very useful and has functional value, not just speculative, say it becomes very expensive. What is to stop someone from just creating their own coin that is the almost identical to it, and using it instead, so high prices are not paid for the other coin? How can all these coins maintain high values, when people can just create as many new coins as they want?
Nothing can really stop such coin from becoming famous and overcome other similar coins. Once people get to know that the coin has good creative idea, it gets unstoppable. Such coins usually never fail in market and can retain high values than other altcoins.
However there are many coins seen which fail later when they list on exchanges because of developers low support and other things
