I think the Bear market is good for buying coins and trading with them. An expert trader always prefers winter for the trade. But If you are losing money in trading then you should stop trading and learn more how to proceed! Without lose, you can not gain in trade. So, I would suggest to do trade with a low amount of money, learn first.
Knowledge and experience are the best tool to succeed in trading. You can't acquire those things in just a day but you have for a months or years. Of course, we do buying at low cost and make trades when it goes high and gain profits. It is just simple but you need to analyze also the market cause of its volatility.
