All the established crypto channels/advisers keep telling everyone to buy the dip and sell the highs. What they don't (and can't!) tell you is where those points are. I have bought the dip continuously for the last two months, and am slowly running out of money. If the dip doesn't stop dipping, I'm gonna run out of money soon. All fun and games, until the bank takes my house.
The policy that guards high risk investment like cryptocurrency market and other market like stocks and forex market is this "do not invest what you can not afford to lose" this should always be at the back of your mind when investing in any of these market this is very important. Also trading requires a measure of experience which comes from training this suggest that for one to be a good trader he or she needs to receive knowledge that will help him or her to master the technical and fundamental approach to the market which in turn will help you to know when to buy and when to sell.
