I think it is definitely investment when you realized what real value it is.
People always say, you are gambling with your money. Crypto is a bubble! The most reason they say it like that is lacking of info/data that what caused coins up and down.
According to Investopedia, Gambling is defined as staking something on a contingency. Crypto is still young in final market. It does look like gambling because people have no clue what things really matter to it.
We should watch its true role in final market.
Cryptocurrency in general could be like a new version of gold, a digital gold. The price of this gold is sensitive to politics, economics, tax regulation of itself. This is a potential safe haven that is not directly controlled by a central bank. It would be its main value.
What problem comes up is governments want to control it, more and more regulations will be a burden to drag down the value of the cryptocurrency, the decentralized system. This would be main reason devalue it.
When governments tighten it up, the value of its decentralization get hurt, it won't be good investment.
