as simple as I know on the bitcoin chart there will be support and resistance, we think of it as a fortress. if the support is broken, then there is greater selling power, then there is a possibility that there will be a decline again, and if the resistance is broken, then the price is likely to move up, and the trend will be up, so we can look for prices to buy. but for that you need to learn with the experience of reading charts continuously, because sometimes it doesn't match our analysis, and we have to have a strategy for that
