Are all crypto projects listed on coinmarketcap used for speculation purposes only ?
For the majority, the answer may be yes, but not for all. Essentially though it is, some are not only used for speculation. Suddenly we already can not expect that crypto will be used everywhere. Just remember when it was used in darkweb, now we have places we can use any cryptocurrencies as payment, and after some time we will develop further, and it will not be used only for speculation.
Cryptocurrency has its own capacity to grow depending on the demand from people who belongs to it's desired community. How come it was speculated? Coinmarketcap was just a website who handles the monitoring of each and every coin's progress, pertaining to exchanges volume in trading. Furthermore, there's selected countries who have been using crypto as their mode of transactions that's why adoption also increased simultaneously.
