I have been waiting for Bitcoin to reach $3000 so that I can sell my Bitcoins, but seems as if it doesn't want to reach that value anytime soon. SHould I sell with the current amount? 
Dont sell it.Just hold.We all too expected bitcoin to cross $3000 by this time.But when segwit will be activated on August 1st,it would definitely trigger the bitcoin price and bitcoin would cross $3000.So just wait a little more.That's right at the end of every year we have seen massive growth in the price of bitcoins and we can expect that from this year too and may be we will see the price of $3000 before the year ends so the best thing would be to hold bitcoins till it reaches to that price as that is the best price to sell bitcoins.
