The best way to buy altcoins in a bear market is dollar cost averaging, you can't predict the bottom of the market so when dips happens use part of your money to buy and wait for another dip to happen, it might be in the next two months, no need to rush things up.
Buy slowly, that's what I do if a bear market occurs. It's true we don't know when the time is really right to spend our money to become an advantage. If you hurry then the risk will be greater too. If we buy slowly, we won't be left behind when the market is going up any time, and we won't be too worried if the market goes down further.
Agree, and your opinion about buying slowly has become a very meaningful lesson and an education that I really appreciate, by understanding your opinion I gain a little insight, and about the right time to buy it or to invest in Cryptocurrencies either Bitcoin as well as other Altcoins, and the right time of course is where the market is experiencing a bear market (Bearish) or conditions that are declining as seen from the graph moving red.
At this time you can just use most of your money to buy it and make it as an investment and keep it as a digital asset, with this it is likely that you will get a profit that may be large.
