I am a bag holder of Bitcoin but I am not a Bitcoin maximalist. I cling my self in a coin where I can get a profit. So far I am trading half of my cryptos in Alts, the other half is BTC.
Yes, it is true that large bitcoin holders are big believers because they invest and collect much bitcoin because they believe that its price will go up and they will gain profits. But there might be another situation when a person who believes in Crypto holds Large amount of Bitcoin but other Cryptocurrencies too..
