Staking is only good when the value is going up or does simply had the potential on rising up on the future plus staking does really have that small APY's but there are some altcoins and platforms do really offer those

huge and to good to be true apy which would really be giving out some doubts if its legit or not but overall its up to someone if they could bare out on the risk on holding their coins on a platform on a long
period of time.
Overall when it comes to investment then it would be depending on someone or preference since not all would really be  that confident.Some do pump and
some do die in the end which its always been hard to predict since from the start.
