nothing . alts have thier own life . if people only sells thier btc then btc is the one that could fall but alts are still stable because they dont sell thier alts but if the scenario happens to be different , let say people will sell both of thier cryptos ( alts and btc ) then this should cause an overall market dump but the chances are low since most people know are hodlers . in case the price drops due to some sellers , ,buyers will still take that oppurtunity and the price will regen again
You're wrong here, once Bitcoin crashes and back to $5000. Alts will suffer a major decline and even some of them are going to burned out. Remembered what happened with Stemmit after Bitcoin crashed a months ago? they fired 70% of their staff and struggling. And if Bitcoin reaches that price again, that explains people is starting to doubt it and the demand is decreasing. If people think no matter what, the price will eventually go up, then why people do not buy it right now?
The project decisions can't depend on the investor's opinion, the market circumstances don't dictate in every project. The struggling projects can fire the developers and this is somehow understandable. Bitcoin can go to $5000 in single candlestick but not all projects will go to all new assembling. Maybe the market will punish the weak hands which can't command the invested projects but strong minds know how to handle the temporary market trends. The focus is important in this example.
People don't like to hear the truth, they like to see the realized predictions. The market is not only controlled by the logic, but the emotions also move the market mostly. The only logic is not sufficient for understanding the price velocity, emotional traders are like the middle man between the changing market trends. Half of the traders may not agree with my statement, there are a lot of variables that explain the pointed approach in the market.
