As you see now, Cardano coin is existed on TOP 11 in the market and despite its price is pretty low ( less than $ 0.06 ) but actually, it has a huge value of market cap, that's the most important thing, I guess this is good chance for buying a big amount of this currency ( between $50 and 100 is okay ) , but don't take the risk through wasting all your money on Cardano because except Bitcoin and Ethereum, there is no guaranteed profit and safe, that is my own view.
Furthermore, I predict that after the halving of Bitcoin, Cardano will rise to $ 0.1 or 0.2, due to this coin is certainly centralized and linked to BTC.
The same thing with ripple its not that valuable but it's inside the top 10 from CMC, Cardano have a huge potential since there are supporters
who are working behind this project, if you are aiming for mid-long term investment this asset is good for waiting, chances is high for this coin
to ride with bitcoin halving.
The current value is good to start your investment, just spare the money that you are willing to risk then wait and hold your coins.
