If you are long on Bitcoin, Hodling vs. trading, then buying at the current prices (hovering around 7k USD per BTC), is smart.
I have some cash, and definitely long on Bitcoin, so I will be buying more. Not all at once, in case it drops more. I want free cash available to buy more.
There is some fear that regulation is coming, and Google and Facebook are restricting Cryptocurrency ads, but Bitcoin is still viable and useful as a peer to peer trading mechanism.
In the US, we have a strong Fiat currency, the dollar. (perhaps you have heard of it?). Bitcoin shines when the Fiat, or local, currency is not strong, and fees and bank charges are large. Think Venezuela, Argentina, South Korea. Bitcoin activity in these countries is large, and growing. Those governments can just print more fiat currency (which makes for rampant inflation) making Bitcoin a viable option for payments and moving money around. (This happened in India, where their fiat currency was briefly worthless).
