Most of the top 100 cryptos are already better than BTC. Bitcoin was the minimum viable product. Check out Dash, NEM, PIVX or even Digibyte. They are all simply better. I only got into blockchain this year and I've never held any BTC for holding purposes. It has utterly weak fundamentals. BTC actually had negative adoption this year (https://www.dashforcenews.com/bitcoin-abc-lead-dev-2017-is-the-first-year-with-negative-bitcoin-merchant-adoption)
I should also mention that I only have contempt towards the BTC devs. Dash is heaven in comparison. Wall Street never bets smart. If they did we wouldn't have had a dot-com bubble or the housing bubble.
