A more correct formulation would sound like this: Altcoins is the future! I think that the altcoins will become a real flagship, driving the industry to a brighter future!
In the future we will see Altcoins fly, for now the dominance of bitcoin is still very strong.
Once people get more matured in the crypto, it would bring bigger opportunity for altcoins to get discovered and we will see more money will come.
I do not think so because altcoin value increased so much in the past. Instead, I think the next trending can become the trending of blockchain to apply in the system of any field. The security is always the problem of any system if want to against attack from the hacker. Every year, a lot of companies spent much money to keep safe their data. But blockchain can save that amount with the system has enough users to guaranteed the hacker cannot have the same capacity to create an attack.
