Why should i invest in bitcoin or other cryptos ?
If you buy land, each year even if you don't work it you get weeds ... if you dry them you can use them to make a fire ...and in turn that generates energy ...
Meaning: that piece of land is giving you a dividend each year .
Where's my dividend if i invest in crypto ?
If you have to ask that question you aren't ready to put money into crypto. Its not for everyone but there are plenty of "investments" that don't provide a tangible product back. If you invest in Amazon stock you are looking for that stock to appreciate over time. Same with bitcoin if you are using it for an investment. But again by the nature of your question crypto isn't for you...yet.
