now a lot of new coins that appear, the price of its kind, there are cheap, and there are expensive, my question, whether this new coin will last long?
Simply asking if a coin will survive doesn't make sense.
What you need to do is do a deeper analysis of the said coin and decide using important characteristics whether or not the coin has potential to succeed. As a guide, you can look at 1) the coin's purpose, 2) the development team's qualifications, and 3) the marketing strategy.
