All are in the green zone for the price of many Altcoins and if we would investigate for a bit we could see that if Bitcoin is on the green green, grass of home, so in effect are the Altcoins as well trailing on BTC's coattails. Not all of the Altcoins obviously are in the green because some are stagnant but waiting for their own moment to shine. That is just basically what is happening and the good news is that almost all major altcoins would increase in value.
That is just my assumption to the matter because some altcoins would get lost over time as some people would take it to their graves or a hardware wallet seed getting lost by their owners or a wallet in a computer getting lost with the computer itself. It may take a while but that is what would happen like in case of BTC where a fraction are already lost because of the said events from its owners that had no clue then that Bitcoin would reach these current prices.
So as a cryptocurrency enthusiast especially for Bitcoin we just have to promote it to other people who would for themselves get some of it to store so that they would contribute to its scarcity. Scarcity is the major factor in making the Bitcoin's value high because of course of the law of supply and demand.
Now as people would buy now and sell later, it will just invigorate the crypto economy because for the most part they would buy altcoins with their profits. Other people will do the same and thus the engine of buy, sell, and trade cryptos would be likened into a snowball that is rolling downhill, it gets bigger and stronger in time. That is how I see things is working and would work in the crypto economy so it is still good to invest now while the prices are relatively cheap because BTC's value will continue to grow that will surprise us in the future if we look back at this point in time.
