How much is BTC pumped up by altcoins?

If you trade like me with altcoins / shitcoins you will know you usually can't change them directly with fiat but with BTC.

So BTC is a sort of passage currency for all altcoin buyers (not the mainstream ones)

I personally think this could be one of the reason BTC is costantly growing and will not stop climb so easy - it has a wide network of "pumpers" costantly expanding

What do you think about it?

PS. please stay away crypto-tards like "BTC is a bubble the end is near" as well as " fiat will not exists anymore in 1 year welcome to the new world"

That`s why it`s been going up so much, because more and more people want to get in altcoins and BTC is the way to do it.
It will continue to go up next year as well, because just now people see big gains and want to get into game as well.
