That possibly happen again. All crypto currency has a volatile value also. In that case we cannot predict all crytpo coin's future either it will goes to the moon or goes dipper to crash.

Alts will continue to crash fist need BTC rise than come alts not before unfortunately. Market move in circle

There is a reason for me to believe that it is true. As far as I can see, bitcoin goes down and modest value, some altcoins have a very fast increase in value. And when bitcoin goes up, the altcoin value goes down in a weird way. If this really means that they have sold altcoin to raise their btc.

Some great points made here!

Many newbies get involved and do not research coins before investing, seen so many crap coins get pumped and then many left holding bags at the top wondering where all the money went.

Please do your research and invest in coins based on road maps, team, pain it solves, coin supply etc.

Current coins way undervalued at the minute (In my opinion) include.....

QSP
AXP
TRAC
VEN
UTK
TNC
ACT
STEEM

Also regarding the continued drop we are seeing has a lot to do with this which I saw today from Alt Coins & Beyond..............

The Mt Gox lawyer/Trustee that is assigned to selling the Bitcoin per court order is doing it at the same time each day (most liquid time)....We're in this until he gets the amount he wants & seems to have a set amount for each day he's allowed to do.
He refuses to do off market selling/auction so as not to affect the Bitcoin price.
The fact that the market keeps trying to bounce back after such huge one time dumps is impressive (I day trade Bit so watching it 24/7 on my screen) but this could take us down a bit until he's done...It's good for the market to redistribute & lower the price but it's hard to watch & wait idle while this plays out...But at least we know what, when, how, etc.

We already seen this before and if you have a weak hands then maybe, its not just 50% that you will be losing but definitely will increased if you don't hold. It's really hard to handle emotions especially the recovery of the coin takes months but we should be strong enough to face this sudden dip.

Yes but the question is when? After the ultimate dips that occur during last Dec and Jan by this year in which all coins were affected, it was just revealed that the cause of this was Mt Gox. In which they sold a huge volume of BTC and BCH before the great dip in which it result the price fall by Dec to Jan. It also found out that they have BTC and BCH left at their disposal which i believed that in the time that they will dispose them it will cause another market price to fall down for sure.

Maybe altcoins will crash again, if the price of btc is going down too.
this is a effect of bitcoin, many of altcoins is down if bitcoin is down. it is better to wait and see what happened later.

If the BTC will go down or, as you said, crach - yes, altcoin will cruch too
Because todays situation with altcoin is based on BTC
It will continue untill in one day gods of technologies will give us another one thing which is more powerful than BTC if briefly
I think BTC will be changed by smth more useful in 1-2 year
Maybe 3
