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 have not mentioned here which coins you are planning to buy. If you mentioned it, it would certainly have been analyzed to see if it was worth investing in at the moment. But if you want to go with Ethereum then keep going because there is still a good time to buy. Also if you want to go with XRP Dogecoin then I'd say go for it there is still a good time to buy XRP Dogecoin.
His post created 2 years ago and with OP isn't coming back then this is an obvious thread to spam and not generally asking for concrete opinion , imagine asking the forum but not to give what have he bought since 2years ago.
That person doesn't not understand cryptocurrency market and don't follow that person to invest in cryptocurrency. The best time to invest in altcoins on bitcoin is the Bear market. When the price is in the dip. But in the dip and hodle to the next All Time High. Once you know that the price is down then it is foe you to look for money and buy. Or you use DCA method to acquire every week or month. Don't follow unprofessional cryptocurrency market experts because they would misdirect you for you to either missed out or you don't have money the they asked you to buy.
that is why he is asking right? because if he knew this market then we are not talking here now , and also you are talking about DCA but have you told him how?
