I think that altcoin is just a crypto complement for a trade, and in the end everyone who has altcoin will be swapped on bitcoin. The very high bitcoin price it can make a lot of people want to have bitcoin as a way to invest in the future. This can be seen from the trading index altcoin and bitcoin so many choices in the likes of many people as a way to invest.
This is true, unfortunately, that's the only way most people see altcoins now. They earn it through different means like campaigns or airdrops, but in the end, the goal is to have it exchanged for bitcoin wherein the bitcoin will be the end cryptocurrency that they will use for trading or investing. Basically, in that sense, altcoins only stand as a door or portal for people to gain bitcoin. Every person may enter different doors, but in the end, the last room you would be in is the same. In context, even if one may get different altcoins, the end result is to convert it all to bitcoin which has the best chance of profit amongst all cryptocurrencies in the market.
Yeah Bitcoin is the foundation of all crypto currency all ICO is dependent to Bitcoin because bitcoin most recognized that is why the price is soaring high

early age gold is being used to buy anything but since gold is metal have weight it is difficult to carry and transfer that is they invented paper money that guarantee payment with equivalent amount of gold.
