When you are depending on that graph you need to have a more time so you can really manage not to lose money in trading and save some extra bitcoin in the next dont panic when the price is low wait for it always to be high again and everything will be fine.
waiting for the price to rise high sometimes just working is it does but i'd prefer to cut lose if the specific coins seems don't have a good future to prevent from having such a big lose like zcash which had been falling down recently from 1btc to about 0.3btc and that's such a pain in the ass
That's one of the reasons to stop investing based solely on hype. I will not say that zcash is a scam, but it has been overhyped, for months, and the launch was a tragedy, for most investors. I think only a few insiders and lucky users have made a good profit out of it.
I agree with you, if I experience like you I will sell the rest of the coins, than the money I did not return everything, better I sell the rest of the coin, even though it's a big loss.
