I planned to buy some altcoins now that we are in a bear market but someone I knew is telling me not to, that its possible more dumps will take place, my question is how will I know when it's the right time to buy coins?
You absolutely need to take some of the funds and buy now, maybe as much as 50% since BTC is also very low. If prices go lower, you get more chances to buy and, even better, when the market bounces a bit you can combine short and long-term strategies and take many quick profits. Don't miss out!
