I think that it is better to invest more, but not now, and wait until the market falls even lower. I think that Bitcoin will still reach the bottom and its value will be approximately $ 2000, but it will quickly bounce.
It is difficult to predict and catch the bottom is even more difficult , it is better to buy at each level in order not to remain in the future at all without buying, I think from the Deposit invest 10-15% at the levels set for you and you will get a good profit!
