For me bitcoin is my number one cryptocurrency and will always be until another coin can replace it from the number one spot. We always want to follow the winning team it is obvious many people will also pick bitcoin ahead of other cryptocoin.
Everyone would love bitcoin from the beginning they knew crypto, then they try to hunting it and found bitcointalk forum, but sadly what they get is ethereum. Because at this time it's very difficult to get it for free, he is so valuable to the smallest number, all that can be obtained for free is the alt of bitcoin.
