I cannot say that all altcoins are legit and good for investment. Many investors are being scammed by fake projects, according to reports. So traders, investors and bounty hunters should stay alert before investing in altcoins. They must conduct researches, view whitepaper, project team and technology beforehand.
Whoever says all altcoins are legit is seriously dreaming and living in fantasy land or probably the person is new to cryptocurrency and does not know much yet now that most altcoins that we now have are just there to take money and close down the project, and this season where we no longer see much of big investors willing to consider any altcoin to invest in, and you see that majority of the altcoins that are doing quite ok still are the ones that is like within the top 50 coins.
I think new altcoins will no longer get the chance to enter the market that much except the ones that has to go through IEO platform, those ones are still under the hype of IEO which has really been working for them for a long time now, and to invest in IEO is not that easy for common man.
