I had several thousands of these coins when they were worthless - don't even remember buying them to be honest! I think I just paid $10 or so when they were priced a few satoshi each.
logged into my account at the start of the year and was very pleased to see that my stash had grown in value substantially, had around 2 BTC worth!
I sold of a good few as I had no way of knowing whether they were just going to become worthless, and couldn't afford to take the risk (at the time - needed money for bills etc).
Now I have about 500 left - I am going to hang onto them for now, but should I be investing in more? Anyone who is not affiliated able to give me an appraisal of this BATA coin's potential in the future?
To me it sounds like you answered your own question.
You were able to make a $10 investment into 2 Bitcoin. Imagine what that $10 investment would have been in the future if you did not sell.
It's not hard to find out what the future of BTA is going to be - just read the whitepapers - bata.io/development
