I don't think you are going to have a year or two to accumulate. Everything in crypto moves faster... either this ship is sailing and worth billions in 2 years, or its bouncing along the bottom and something superior has replaced it.
Yes, there is absolutely a scenario where BTS goes exponential once a minimum viable feature set and gateways are available.
However, I am betting that no 2.0 tech is really going to lift off until BTC goes through another market cap expansion into the $10k - $100k range.
BTC is being held back until the ETF and perhaps the NASDAQ folks get the pipeline opened up.
Once the next round of fiat value is converted to crypto the BTC wealthy will go hunting for the next hit - and some yield.
At that point BTS becomes the obvious choice - move BTC value back into stable assets (bitGold, bitUSD etc.) to store/preserve wealth... and earn yield while doing so.
It will be and explosive and revolutionary paradigm shift in global finance.
T-2y and counting...
