No other best for me except bitcoin and that's ethereum. As far as I know, many says that ethereum will be going to become as what bitcoin is. Ethereum got its best also interms of market value and popularity.
There are many options out of bitcoin and i have many of them i like as my asset. But i can say etherium and Neo are good choice. Currently cryptosphere in china is being dull but we can say for sure after dust settles. NEO provides GAS which is an interesting concept and will draw a lot of people into NEO the higher the price goes. So Neo is also good choice.
