ETH/USD To buy everything to sell at the same prises?

Uncle with big money, there is no point in buying ETH from $ 300 to $ 84, then to sell it at about the same prices. ETH is currently a good investment for the next few years. The longer we are in consolidation at the bottom, the faster we will go to conquer the prices of $ 400-600-800-1000.
The best option is to buy ETH in equal parts every month.

I apologize for my English, I know it very poorly and I have to translate the text in online translators =)
