I gonna go with NO. The Bitcoin ecosystem is still developing, making it possible if not likely that Bitcoin itself will continue to evolve over the coming decades. But I think your worry is defenitely not out of nowhere. Because however Bitcoin evolves, no new bitcoins will be released after the 21-million coin limit is reached. So if you mean an end in this way, it do make sense :)However, it is not yet, I think.It is not approaching its end.
