If Bitcoin reaches a price of $ 100,000, then the remaining cryptocurrencies from the top 10 will increase in value significantly. In this case, we will buy Litecoin for $ 1,000 and this is far from the limit.
Of course, if Bitcoin costs $100k, we can see Litecoin at $1000, ether at $2000, but after what time Bitcoin can grow to $100k if it can't grow its ATH yet.
