Well maybe newbies really need to learn from their mistakes to know when to sell and hodl their bitcoins. If they experienced failure and mistakes from their own actions, they will be able to learn from that mistake and from that day on, they will surely know how to handle their coins, and maybe, they will also buy coins instead of selling their coins to earn more profit.
Trade in different way, Treat short term trades as binary options, Other traders are trying to capture a move, but instead you are trying a defined bet. When you have a bad trade don't close it immediately but instead set a random timer to automatically close the trade within a defined but short period of time.Try random delays for entries as well. If a trade does'nt work out within a define time, close it out It probably was'nt a good price or opportunity if its still available after some time.
