Bought the first coins in 2011 around 3$, where unsure, young, did not really got into the game and invest time, just trade them over the years with more or less small profits, felt lucky and sold them finally in times of fear. Didn't hold 1 Coin left, stopped a while and after checking the prices a couple of weeks ago I still want to smash my head against walls
So, from now on my strategy is clear. The feeling I have from what I know and see is the same I had 6 years ago. Unsure, but worth the risk. Even better, because I really begin to understand know how what bitcoins are, except from earning money. Now got enough trust over the years to spend everything I don't need for living and can lose in bitcoins ( ~ 80% / 20 Altcoins) and -hold- the most amount this time. I'm ready for the next 6 years. In meantime I have time to do better research, watch the market.. trade little amounts.. and will resist the temptation trading to much and selling to fast. When you lose it all but still can say to yourself, I really thought about it and this way felt totally right, I don't regret.. than it's a good base for your strategy I think. That's what I learned for the future. Good luck guys!
