Nobody knows for sure, but here are my best guesses.
Bitcoin- Bitcoin will be number one because it is the crypto-currency that everyone knows. As more and more people become involeved in the crypto world, they will use bitcoin. Bitcoin is used to switch between currenciesand is currently available on amazon.
Something that is not out yet- Most likely some genius will develope a crypto-currency that is better than all others. The tech would be unbelievable.
Antshares/ Neo - Antshares/Neo is very impressive. It is developed by a Chinese company and is like the Etheruem of China. I believe many people in China will invest in this.
Nice post. I think in 10 years, a lot of things could happen. However, Bitcoin would be my first guess, too.
