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?
what i can say here that if you are asking for some sure thing on crypto then you are really wrong on this because there is no such thing on crypto. All of these coins are based on some speculation and it is always pump and dump, you just need to be lucky enough to get pumped and being unlucky when it is dumped. High volumes are depends on demands so whenever there is demand price will always increasing and that apply vice versa
you are right that there are many questions comes in mind about long term prices because all the life activities are connected to the price of bitcoin and need to be sure about all the features about bitcoin before invest for the long term of price, there is permanent in long term and those people who will proceed and earn profit then that person will be lucky while when dumped and earn nothing than one thing happened and that is bad luck.
