I don't agree with some of the things you say here. Litecoin is, in my opinion, very heavily dependent on Bitcoin vs most other coins such as ethereum, xrp, xlm, etc. Maybe even more so than BCH due to it(LTC) being basically a "fast" Bitcoin for transactions. I think what you say about it being a better bet than Bitcoin is simply not true, LTC is essentially an equivalent investment to BTC. If you want to diversify crypto assets definitely don't put too much into both BTC and LTC.
