Let me rephrase my question again for better understanding: Which signals, what techniques, which movement do you consider while making selling decisions so that you always make best possible profit in the given scenario? If I chose right time to sell my futures, I would have made 10 times more profit.
You're not in this alone as I'm still finding it difficult to get my predictions right too either I'm some Satoshi late to buying or some Satoshi early to selling. Late week I bought some coins very late and sold very early too. This trade wasn't a profitable one but since I sold too early i missed out on cutting my lost by almost 20%. Looking at the coin now it's almost -150% down which is a relief since assuming I decided to hold unto my investment, I would have made more lost then what I exited the market with.
Can I know what do you mean by decline of 150%?
Say, something worth $100 and we say it is increased by 150% then the thing worth $250.
But what would be the value if it declines by 150%?
I use the system where decline cannot be more than 100% but I have seen several people using negative percentage more than 100%, how this system works?
