it mean if you are a daily trader,do not put too much your hope into it because you can not predict the market and nobody can predict it.
do not living your life using that trade and always use some of your side money into it.
you can double your money in the next morning and you also can lose it all in the next morning.
a lot of trader lost all of their money because of it,they put too much hope and dream in their investment.
and when the price is down because of the whales he's panicking and sold his belongings.
he did not know it's a cycle,right now you can see it's below $1 but a month later you will see it at $100.
everything is possible in cryptocurrency
