We have yet to see the end of 2018. Of course that correction was inevitable, keep in mind how fast the prices went up in December. Correction was expected to occur. However I do believe that for the long run it doesn't matter as the market will catch the bull run again someday in the future.
Correction is always normal in every market. Ethereum has a low to about $300 recently and then bounced towards $700 with some correction afterwards and there we are with some noob declaring 2018 as a bad year for the whole market.
The OP sure do have some point on the volume, but we all know how the market can act at times, as all traders are simply looking forward to catch the best gains most of the time but only time will tell if this is just going to be a little retrace or we are up for some crazy moments ahead.
