This is completely true and in a way logical,there are very few assets be it equity,crypto,etc. which have potentials to give good returns.For traders a 5% return is considered good and equity investors consider a return of 12% to be a good year.
There would be very few people who wouldve voluntarily left their money invested without forgetting it.And in all fairness it is logical a 2x-3x return is excellent and we can always re-invest instead of hoping for a 10000x and hoping for a miracle.
