We are still in very early stage of Crypto Currency investment. There would be many ups and downs maybe big dips as well. However in long term there is only way UP.
This correction can present great opportunity for long term portfolio building. I look for solid/fundamentally strong coins. And if ETH dips below $200, I will go all out in ETH. This is a solid long term buy/hold, my prediction will be $1000 for ETH when dust gets settled. There are many organizations/institution backing ETHEREUM, they will not let it die.
