Cardano.ADA is another smart contract platform similar to ETH.The basic purpose of ADA is to use block chain technology to bring banking systems where they have previously been to expensive to implement specifically to developing world.Ada is currently traded at a low price and is easily affordable.Investment in ADA and to hold it for long term would be extremely profitable.
IOTA. MIOTA addresses the transaction fees and scalibilty issue of block chain technology by getting rid of block and chain.In MIOT there is no need of miners to power the network.MIOTA promises free fast transactions.It would facilitate whole machine to machine micro economy.
So both the technologies in both coins are worth of importance and developers are working constantly behind them.Currently both are traded at low prices and investment in these two coins would be highly beneficial and hold them for long term when they would be at maturity level then price would be immensely high.
I don't think that Cardano and IOTA are really competitors. The only real similarity is that they are both new projects that are also very high-profile. Cardano I would say is more of a competitor to ETH, NEO, etc. It certainly does look promising, but the price at the moment is based largely on hype. Similarly with IOTA - IoT is obviously going to be huge, but compare the IOTA price with that of IoT Chain (which arguably has better tech), and it seems that the IOTA price is also based mainly on hype.
I'm not saying either is bad, and Cardano I definitely do like - but I think there are plenty of underpriced coins that are better investments at the moment.
Well, I wouldn’t say either of the coins are based on hype and are overvalued. Though, many low valued coins might have better technology than ADA and IOTA and are likely to succeed in near future, it’s not always the technology that decides the price of the coin.
There are various factors that decides the price of the coin such as development team, team of advisors, their transparency, their support, their partnerships, their updates about work and many others.
According to me, ADA and IOTA both are still undervalued coins and not at all under hype. These are most likely to grow at least by 5X by the end of this year 2018.
