BTC made great run to be honest at that time, it had the best performance too among all the crypto market, next to BNB of course.
In My Opinion, the next bull run of the whole crypto market will start by the close date of the BTC halving (May 16-2020), this wave won't be as fast a of late 2017, first 2018, but it may take couple weeks or even months in a steady Bull Run.
BTC may dip even further to some great cheap prices (5k or even below) again before we see it rises again to start it's new Bull Wave that may break the last All Time High. This (IMO° may take us to even 2021 to accomplish this scenario).
YES, YES, YES, it's a great investment deal even from today if you're an investor willing to throw some $$$ for the next 2-3 years.
