Maybe what you are saying is true, it is too rare that anyone can survive more than 10 years in the bitcoin market. but there are those that still survive and it must be admitted, we can be sure that they have devoted themselves to finding a life in bitcoin. because if there is no definite goal it can be said that they will stop themselves from boredom.
Being too long in the market does not a security mark for any profits from investment or tradings. There are losers and winners and the capital flow on the market are moved between losers and winners. They can survive after few years and they can get big wins or big losses sometimes but not all of them can end with a profit. Bitcoin market is risky and your greed and bad leverage orders can wash out all you achieved after years.
especially when from mid-2018 to the last few months bitcoin was in a sluggish state. so that many are no longer active because their income does not match their work.
is currently experiencing an increase and the possibility of many returning to join again. because this is the time the opportunity can be done. but until when? no one can predict with certainty.
The 2018 is a first bearish year of bitcoin after it hit all time high in late 2017. It is a boring year and I remembered the month when it fell down from strong support around $6,000 to below $4,000. It is a terrible month and worse than the crash in 2020 as a pandemic consequence.
