Market conditions like this are what many people want in investing, almost completely the increase in bitcoin prices affects existing altcoins, even if you look at market conditions, almost everything is on the green line, the bitcoin trend will continue in the market, if in a few months it continues to improve and it is likely it would be above average for all the coins in existence, october is a very good month for anyone with previous investments.
I would say that market conditions are exactly the reason why people end up selling eventually. We have increased like crazy and right now it is not doing something anymore and it is getting to a situation where it would mean that people will start to sell the things they own. I mean right now crypto is not making you a lot of profit, not in the past week or month but NOW and that means the most important thing.
You have to realize that market doesn't have any emotions, market doesn't care if you are about to pay your mortgage or you are about to pay your student loans, the moment market realizes that they are not making enough profit then they are going to start selling everything which looks closer and closer right now.
