This statement is very difficult to understand for a Newbie in Trading.
Many newbies consider this in their earlier stage of trading, for which they face huge losses.
They forget the basics of trading and in anxiety they take wrong steps while choosing the perfect coin and perfect time.

All the above mentioned points by the OP is well written, but I would like to emphasize on one specific point.
Always choose the right exchange or trading platform.
I have seen many newbies joining scam exchanges due to it's attractive marketing and hence losses their money.
At last I wish all the traders to make huge profit and live like a King's life.
