True. Many people nowadays are in it for the money, rather than waiting for a specific cryptocurrency project to become fully developed and functional in the real world. If an altcoin is slow in delivering good results to the real world, then investors become desperate and shift to other new projects. But, those who're patient, will be able to see outstanding results with their investment as they become rich in the future.
If we were to choose a good altcoin to buy right now, I'd say it would be Ethereum. It has the largest ecosystem of tokens and decentralized applications unlike any other smart contract platform in existence. What's better is that Ethereum will scale and improve to become a highly functional Turing complete smart contract platform in the future, having a positive effect in its value in the long run.
All in all, do your own research and you'll see why Ethereum is the best investment to make for your financial future.
