I think for 3 years later, cryptocurrency is still a profitable thing. we really can't predict it but I believe that cryptocurrency will be good for the next few years. the most important thing is that we must be able to use it properly so that we can get the benefits.
cryptocurrency 3 years later will definitely be a good technology and provide profit. I'm sure crypto still exists in the next 5 years. so I will not doubt the potential of crypto in the future.
