I do not look at it as at some addiction. It is normal to spend a lot of time and effort on researching and monitoring the market if you really want to get to the level when you make enough money for your life just from trading.
It actually depends a lot on the circumstance that you are at. Like for example if you have some significant amount of time you start spending it all on trading and as soon as you see even a little of profit you may get more and more addicted.
It all depends of what kind of savings you have at the moment. Just remember to stay safe and do not invest the moeny that you have for your every day life and needs. The less you invest the smaller risk you take. So just go step by step and invest more every time.
There is no a particular amount that one should spend when investing in cruptocurrency and that is a hige advantage of this maket. You can start like with a low amount and with some effort grow your capital.
I simply would never keep my whole capital in the bitcoin value only because this is way too risky. At this point all you can do after such loss is properly analyze what was wrong and which software actually let you down.
It all depends on what strategy you have chosen and what goals you set for yourself because if you decide to go for long term investment then you wait for the bitcoin's value increase otherwise you should simply go for day trading.
I am sorry for what hapeden to you. And I strongly advice everyone who has just joined the bitcoin community to research before getting to the market and make sure you are aware of the risks you are about to take.
It makes sense to sell your coins whenever their value will get to the point when your potential profit satisfies you and makes you gain from your investments and that is the best strategy to follow to stay successful.
