There is never a good or bad time to buy in, I try my best to buy whenever their prices tank in the hope they will rise again, off course I have no way of knowing if they will rise, it is just blind faith.
If you use your brain and understand the mentality of trader on market, the think of big boy and whales, you can predict the scenario happening on market and have good decision about sell, hold or buy your coin.
- Personally, I think any time is a good time to invest in bitcoin and eth because this is really both very potential and prices will rise very high in the future. But the best time would be when the prices of both tend to decrease dramatically over a period of time
- However, we should observe and analyze the market to buy at the best price, that will help us get more profit. Always follow the whales, this is my personal experience
For big coins like bitcoin and eth would be better to follow the whales, just how we set the right price to buy or sell, from my knowledge the coin like that have a high percentage to climb back if there is a dump.
