It seems before long you will own a lot, you have been able to amass some alt coin for yourself, well even to me it is an encouragement as well as a challenge.
My advice from the little I have gathered
1.never rush in making a decision as regard wether to buy or sell.
2.get enlighten, learn from others
3.be sure of what you are doing.
4.study the market, the past, present and the possibility of it future.
And so many.
I also have the same opinion with which you point out, is a lot to learn whether it's from other people's experiences or information that we get through reading. In addition, it must be able to learn to control your emotions and learning to wait. because in the long run it often will test us.
