Red market is a good time to buy a few coins, every place of investment takes time so that every investor gets a profit, only a few investment places that promise a short time for each investor to get a profit. So, you can buy bitcoin or altcoin and my advice to you is to choose a long-term investment, don't target your investment only for the end of this year, if you are targeting to get a profit at the end of this year I am sure you will be stressed and sell your investment in loss situation. Buy now and see at the end of this year if the price of cryptocurrency recover you can sell it, but if the price is still the same as now, keep hold is a good solution.
