1.Normally when i buy any coin,i wait sometimes for coin to rise.But when it doesn’t i sell this coin and after somedays it increases and it leaves me thousands regrets.
Like you said, "normally" which happens normally to every manual trader.
It happens normally to beginners actually, well most of the time you need to let go of the this kind of habit coz it is not beneficial at all, when you invest on a coin just make sure that you can take how deep it gets coz that is just basically normal in cryptocurrencies. And also, most of the time you'll regret doing such pulling out.
2. When i decide to buy any coin,i don't study about its chart,so normally i buy coin in their peak.As a result when the price of the coin falls,i loss chunk amount of money.
This I don't do much, I prefer the underdogs which have a history to pump in a blink.
In short, I don't ride the hype.
The hype follower, obviously this is not what being a trader it makes you more of trend checker that do not make any analysis at all. Well in fair honesty, I do this sometimes BUT when the coin is valuable enough for me. Besides, you can gain a lot in a short-term from this.
3.My biggest mistake is panic selling.If any coin falls a little i panic and sell my share.And it cost me some money.And again when it increases,i try to buy.Its not very good.
It's your emotions that is taking over.
Learn how to overcome that. It must always be about the money and not what you feel.
In short take action with dealing to the market. It's normal to panic actually, what's not normal is when you cannot control yourself anymore.
