I am really disappointing. Bitcoin just dont want to lose any value anymore. Only altcoins still does. It seems alt coins are some sort of buffer that keeps Bitcoin still floating. Same as altcoins did not let Bitcoin grow that fast in early 2017 and mid 2017 same now altcoins dont let Bitcoin lose value. This should sort of prolong bear market because it just cant come to the final capitulation before altcoins are totally dried out. Altcoins seems to kill my vision of the September bottom.
I do not think you should be linking bitcoin and altcoins - people own bitcoin for its own "features and risks" and people own say ethereum for its own "features and risks". But the feature and risks of each are very different. so if you are buying and selling expecting some price relationship eg if bitcoin falls 10% ethereum will fall no more than 15% you are going to churn through a lot of your money. I think quite a few people that are into bitcoin own 95% bitcoin and 5% alts - they select 1 or 2 alts with particular features that may make it a great thing in the future. But when they have new money to buy crypto with in many cases it will be all bitcoin even if it means lessening the % share of their portfolio in alts. So alts will always have a hard time (as they should given how many problem most have in the way they are set up etc)
