Nice video by the way. But I dont think altcoin can move faster than bitcoin when it comes to adoption. Yes, cryptocurrency has been exposed and started to gain traction in the real world but adoption isn't achieved by ALL cryptocurrency isn't it?
In my country, there are lots of cool things to purchase and used of crypto, shopping, airline as well, restaurant, electronic load for mobile phones, game credits, and even payment for bills in the house and government mandatory fees.
But only few crypto are allowed and mostly its bitcoin that advanced. Every altcoin out there has used same protocol bitcoin introduced. The point here, not all crypto will be adopted in the future but only those useful one.
It may also depends on the wallet or applications that we are using to determine whether that alt can be used. In many alt that is there. Some is really consider no need as it seems to be the same with other altcoins. Some alts are only made for specific project and may not be easily adopt in different countries that may contradict their tradition and beliefs.
