I also agree with most of the opinions that when the price falls, this is the right time to invest. You have already made your choice in favor of bitcoin in 2014, despite all the negative predictions. Exactly the same situation now. Listen only to yourself and make the right choice.
If the new investors or the old investors will still trust the cryptocurrency market and are still keen on investing in this year 2019, even if the market is in falldown then ,it might be good for long term investment especially the coins now are low in price value, so lets continue to support and invest in cryptos for good.
