BTC trade volume is low because of the transaction fee is too high. It is dominated by the big players now.

I think it's a good start for btc investing a standard price for us to buy and wait for the future to sell it.

Why you all guys worrying about its price whether it increases or decreases if at the first place before entering on this is you probably know about the fluctuation and bitcoin contains a high volatility? Every week im seeing a post about its dropping price like can you post something more interesting ?

I think Bitcoin price decline stage has ended and now it is passing recovery stage after a huge flactuation. Stability is expected. Very soon it may recover its price.

The third bitcoin bubble burst.  The first one was in 2011: up from $0.1 in 2010, x300 to $30 in summer 2011, burst and10 down to $3 half a year later.  The second was end of 2013: up from the previous $3 in 2011, x400 all the way up to near $1200 and burst6 down to about $200 in 2015.  The third one is just behind us: up from that $200 in 2015, x100 all the way up to near $20 000.  We don't know how low it will go.  If history is an indication, down to a few $1000 in a year or two years.  

It is normal bubbly behaviour for a pyramid-style asset such as bitcoin.  The reason is that bitcoin has been, since its inception, a "get-rich-quickly" pyramid game, where you can acquire coins for not much effort in the beginning, and sell them to greater fools at high ROI later.  Each time, you get a larger set of greater fools that buy at the top, and pay for all the benefit of the previous gamblers.  These greater fools get burned, and it takes time for them to accept their losses.  Until they've sold with losses in the market, and heal their wounds, downwards pressure stops from price rising.  When the last army of greater fools has sold out and accepted their losses, however, bitcoin's set for the next set of greater fools, and the speculative game starts again.  Rinse and repeat.  It will stop when one runs out of greater fools.  Potentially, the world's population that has sufficient money to gamble.  

If you're convinced there's yet another bubble in the making (it may take a few years: the periods between bubbles get larger), you might make a lot of money by buying in.  Not yet (even though it doesn't matter: if after the 2011 bubble, you bought in at $15 to see it fall down to $3, you could still have made a lot of benefit at the $1200 bubble ; and if you bought in at $800 after the $1200 bubble, you might still have made a lot of benefit at the last $20 000 bubble).  Note that the next one may take a few years if ever.

If, of course, this has been the last one, you're a dodo, but slightly less than the fools that bought at $18 000 of course

Hey, keep calm, anything gonna be okay. look back, look through history and price of bitcoin you will understand this.

The more you in bitcoin area, the more often you will see the same situation: Dropping price down and then raising up. Last time it was -30% and then +70%

It went too high too quickly.  I am waiting for a big drop so I can buy and make some profit.  And then a lot of people can buy and have a chance of a profit.  Not just whales. 

I think it's just a slack period, nothing interesting right now so the weak sell

Why does everybody keeps on saying it is low.
The problem: We got so much used to the price where it was almost in heaven.
But when you really summarize it, this is still way up.

Before we throw a fuss like this then maybe we should be looking at the graphs.
You will see the bitcoin flow in just weeks while it took months to get up to a $1000.
