the strongest support is somewhere in 6100-6200 that's just what i can see in the line chart. it might just be the very bottom of this so if you want to buy, that's where the best price you get to enter. if the price don't hit that low yet i wouldn't buy, this is my strategy only. don't take this as a pro advice because you might just loss more of your investment. take it as a insight.
But, there is no guarantee that after buying bitcoin will bear market end and later on market price for bitcoon will increase because there is a huge probability that bitcoin will drop for.more and worst bitcoin will going to pop up like a bubble. And this is we do not like so we probably watching how bad market is now would be a good idea and participating later on would be ideal.
