It is not even a good investment decision in this cryptocurrency world to invest in many projects because monitoring them won't be an easy task. As for me investing in like 5 projects that seems solid is moderately cool and it will be very easy to monitor them.
coin price movements that continue to occur suddenly are indeed not a good decision to monitor many cryptocurrency projects because the exact time that will not be enough to do it all, the right choice should not be too much or a little in monitoring the project and only monitoring projects that could potentially continue until the future.
