So if I have just one coin, I will be wealthy?
Yes. But you might have to wait for one or two decades. In 5 years, we got from $0.0008 to $500. Who knows? In another 10 or 20 years, we might reach $1,000,000. Be patient, collect as many coins as you can... and hope for the best.
Note: And most importantly, keep your wallet secure and take regular backups.
