2018; where does crypto go from here?

I started buying crypto currency in March of 2017. I was completely fresh to the concept and didn’t know much about Mr. Satoshi or Blockchain technology.

Litecoin got added to Coinbase and Ethereum was making a good run. It all seemed too unreal to be true, increasing the value of my USD from bouncing back and forth between the only three currencies on Coinbase seemed like it was all going to just fall apart once the total market capitalization raced for 60 billion to 120 billion; then slammed back to 70 billion. After all, who in the world would put their hard earned dollar into such a fly-by-night investment?
Every single coin/currency/token has gone up exponentially since then, and now the total market cap is nearing one trillion dollars!!!! My investments did not follow, because as I have recently read, that I have been investing with a “herd mentality.”
It’s very hard to sit and watch a small amount of money sit for months on end to return to the price I purchased it, and 99.9% of the time I did not spread my risk across multiple currencies because, I want to go Big! Ha. It hasn’t worked and even though this market has gained lots of momentum, there is no logic behind the spikes or dips. The timing of these dramatic price changes have no real predictors or reasoning behind them that the whim of those that move the market with large amounts of money are clearly in cahoots and it sucks a royal bitcoin.
