The market gives two choices up and down, and because people lose because they don't have the patience to hold on when the market falls.
Sometimes holding is also hurting more more than panic selling just imagine about people sold their coins at January 2018 because of panic selling are more profitable than who is holding now so speculation is about buying and selling at the right time sometimes it is just based on luck too.
One thing everyone cannot do is to sell, that is one basic thing with the market, as some people are selling, some people are coming newly into the market, and thinking of holding, and that is basically how it will keep going until we get to hit the level of mainstream adoption.
I know it can be a bit difficult to see what you are holding tank down seriously and then you are assuming if the market will even have any chance in the nearest future or the possibility of even growing in the long run, but you should remember always that at least, if you cannot trade, you should be looking at holding and focusing your attention on the future.
First mistake that people make is buying when price is rising, and they are selling when prices are dropping. Second mistake is making those trades with all amount, top or bottom should be chased, when prices are rising you are selling just some from your stash, it's how you touching the top, price rising you sell some, price rise a bit more you sell again, when price is going down you buy some, price drop more you buy some more, its how you touching the bottom. To trade successfully you need to have back up plan all the time, to be sure in that you need to have good control of your bankroll. If you buy on top and sell on bottom you will lose all your money, you lose if you don't have patience to wait market to move and make conditions for your trades to be successful.
