The key word in your post is “may be.” Before buying any coins, make sure to analyze the project behind each one. Hope you get lucky, but don’t forget to do your research.

I don't understand anything right now. My intention was to buy some currencies and leave them for time, maybe they'll skyrocket like Bitcoin and others. I bought different currencies for $400, and now I have $154. Should I do anything? Does this mean the number of currencies I have is decreasing, or is it just their value that has dropped while I still have the same amount? I hope for help.
