I would buy ADA. Cardano cryptocurrency is not just another coin, but a real technological platform, with the help of which the team of this project promised to solve all the shortcomings of the digital money market and blockchain technologies. So she has great prospects and I think it's a great option for you!
Cardano is definitely a great project but why limit yourself to buying just one of two coins? Neo is insanely low right now and its very safe to assume itll go back to the ATH next run
There was a lot of the same platform as NEO and I will try to predict the price of neo will remain the same consider the demand has already divided into a lot of partials.
It will be so difficult even impossible for neo to reach its ATH again. Is there an important advantage of the NEO platform and I see nothing from there.
