retest of 50 EMA as a support, will it hold ?

BTCUSD at a critical support which is the 50 EMA, it has to held the 3810$ level otherwise it will go to at least 3000$ then to a new low.
In my previous analysis, i said that breaking the 50 EMA then coming down to retest it as support would be perfect which is hapening now.
Again, if the 50 EMA helds, everything will be fine and i can say it is the start of a the bull run.
