The first thing we have to do when the bear market is holding a coin. There is nothing we can do unless patiently waiting for the bull market. Or you can also join the bounty program, airdrop and ICO projects.
There is only one solution to stay away of losses and to stick with profit by buying coins more coins if it is a bear market so you will not waste your time till bull market but this is also benefit to get coins of high potential those generates huge profit for you. Now start buying more coins so that you may make a large collection or hold coins in large quantity so a time is coming when you sell for huge profit.
Not actually the only solution
There are still a lot approach depending on what a persons right way of doing it like what OP's approach
the downside of buying large quantity at bear market is that you wont really know its floor and might tempt you on selling when the price goes down deeper and deeper
Just remember that unless you aren't selling it, your coins doesn't lost at all
