If you can't control your greed and emotions while investing then surely you will lose confidence in consistent investing. Because if you are greedy then you can sell Bitcoin when the price goes up a bit. Experienced investors never lose confidence in their investments, they always think positively about the Bitcoin market and they keep their investments for long term. So all experienced investors can achieve the most success from their investments.
Buddy this emotion of a thing is likely for traders and gamblers whose main aim of being part of Bitcoin inveytment is for quick profit, as for an investor that abide by the concept of Bitcoin being a long-term investment, i don't think such investor has anything to do with emotions, emotion is been attached when one consistently check the market price to enable him or her trade but the thing is all these are stressful, Bitcoin investment is not meant to be an emotional thing, it is an asset thats meant to benefit individauls in a long-term, so anyone going contrary against that is doing what we call trading and it is to his or her detriment.
Mate I don't think it's greed that makes people to sell prematurely during Bitcoin upsurge, I see it as what individuals want though it is not the right thing to do but we can't conclude that the reason for people to sell during Bitcoin pump is greed personally I don't concur to that.
There are people who came for quick profit in Bitcoin investment not that they don't know about Bitcoin being a futuristic investment, just that they are not ready to wait for the said long-term to come in other to achieve their expectations.
