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.
Usually, those points are called resistance levels. You have to check where those points are by simply going to your favorite exchange and looking at the buy orders. Look for where there are the largest pending orders. That will be your resistance levels. Depending on your exchange, this may be simplified by the use of charts. Do this as necessary across exchanges and you will find what point most people have large orders. That is usually your resistance. Buy close to or before that.
