Recently Ethereum has been under sustained attack by undisclosed hacker/assailants. The attacks are persistent and they change regularly, exposing and exploiting weakness after weakness. The weaknesses have allowed hackers to slow down service and deny access to an extent. The ETH coders are working hard to address each attack as it comes on line. The price of Ethereum (ETH) is tumbling as I write.
Sounds gloomy eh? Not to me. I've lived through hundreds of incidents where an IT systems weakness was exposed. In a short time (always seems pretty long when you are in the trenches fixing it) the technicians and engineers would put in a short term fix then resolve the problem permanently as they were able. This is normal. The first cars were so clunky one had to a have a mechanic, tools and parts ride with you so they could repair it long enough to get you to where you were going. Nowadays one can drive a car off a show room lot and aside from routine maintenance may not have a break down for 100,000 miles. It is part of the development cycle, especially the security development cycle.
This is where crypto currencies are now, the cycle is greatly accelerated for crypto currencies due to the high payoff for a successful hack. This coordinated attack, while disruptive, is doing Ethereum a world of good. To me this is a wonderful time to invest in it. One has to time it, you don't need to catch a falling knife but keep an eye on ETH. Sooner or later (i'm reading sooner) the attacks will run out of effective vectors and they will dissipate for lack of fuel. The price of ETH will start to rise. (that's when I will jump in) ETH will be all the better for this attack and confidence will rise back where it was and maybe beyond, once one more development cycle has passed.
