Why I think bitcoin is screwed right now and litecoin probably will continue to go up:
and since Bitcoin has a more predictable supply than Ethereum it can be used as the ideal store of value.
Well, that's where he's completely wrong because no cryptocurrency is a store of value. It's a currency, not money. It even says "Crypto
currency" in the title. Currencies are never a store of value. The only thing that gives them value is transaction flow, which is determined by scalability and pushing through millions of cups of coffee, contrary to what people claim where coffee is the bitcoin anti-christ. Noble metals such as gold and silver are absurdly better at being a store of value (i.e. settlement layer), so there's no way bitcoin and any other coin can compete with them in that regard. The ONLY way they can compete is in transaction flow (where scalability is key). If Litecoin adopts segwit (and it actually works to scale), while bitcoin doesn't, I see no reason to hold bitcoin at that point.
I gave the estimate a long time ago (I'm sure somebody remembers it) that you would need at least 8MB blocks (or around 50 TPS) for bitcoin to be a valid, globally used currency with market penetration into the upper middle class. That's speaking on-chain scaling alone, and at that number, it would probably be uneconomical to do transactions under something like $10,000, but the network would probably continue to exist and not fade into obscurity.
Jihan Wu and the other Chinese seem to have made a deal that litecoin will go to at least 2MB blocks in the future (the equivalent of bitcoin with 8MB blocks), and agreed to segwit. So litecoin seems to have passed the minimum required scaling threshold to exist, while bitcoin has not. Hell, at this point, the optimal strategy for the Chinese might even be continuing to block segwit on bitcoin on purpose to destroy it while investing money into cheap litecoin and profiting on the destruction of BTC as the litecoin they bought for pennies skyrockets.
A similar move was done by the Pilgrims Society in gold vs silver. Most of these rich bankers and aristocrats had their money invested only in gold, so they conspired to demonetize silver, which had the result of being a transfer of all silver wealth to the gold they hold. There is nothing to gain by attempting to keep silver down now, so in the near future I imagine some of these same people will conspire to remonetize silver to drain the money back out of gold for profit, thus screwing China, India, Russia, and the arab nations who bought up all the gold.
Since someone made the bad judgement of requiring 95% approval for segwit on bitcoin, there is also the chance it never gets activated. A government entity, bankers, or whoever could start up some miners and reject segwit while dumping the coins they mine for profit and basically block it perpetually for....FREE...NO COST. Bitcoin will not scale without forking into two chains and having an enormous rough consensus attack at this point.
