We hear on facebook, twiter, steemit, this question you have to ask first is when learning? because if you think just by buying a coin and holding you will get rich the chances are low and i will tell you why.
Lets suppose you bought eth at 8 dollars january last year, if you didnt learn and just bought the coin, what are the chances that you hold it until the atm of 1400 dollars, the answer is not very likely, you probably sold it at 20usd and make 100 and some profit.
We saw what happened on the last september fud, everything went down, alts went down much more that bitcoin and were very cheap but what most people did was sell alts and buy bitcoin. Probably the smart thing was to sell the btc and buy alts back then. After the fud disipated all alts went to the sky. Basically we all know that the smart thing is to buy what is undervaluated and sell what is overvaluated. What is the problem then:
EMOTIONS get on the way and when you bought because you saw and article or a video and didn't do research, and are not convinced that crypto is a good project then when it goes down you sell and loose money. I believe there is a idea people use to justify that is they will buy back low, probably they will never get the timing right and end up buying higher that the price they sold when it all goes up again, and it will, for sure.
What do you think will happen when banks start creating crypto investment fund for regular people, when people that want to diversify invest 5% of their holdings on crypto? This will happen, mass adoption is on the way, we dont know the exact time but it will start this year, so hold to the coins you believe in, sell the ones you dont believe if you are even or at a higher price that you bough and if not wait for the next bull run and sell them then, remember this is a game that rewards the pacient ones and punishes the impacient
