Is LN opportunistic? Sure, but that's a good business model..finding an opportunity and making money from it. That being said, the next part of the model is to make a product that is superior and merging opportunity with reputation. I find myself having faith (hope?) that's what LN has done...based solely on no research or facts of my own. Lol.
As a skeptical bastard, I find myself questioning things sometime far too much...which leads to diminished faith and eventual worry. As a word of advice, don't overthink too much. Trust your research, opinions of others and eventually just your gut. If it all goes south from there, consider it a learning experience.
FWIW, the quoted "50 engines" just doesn't pass my smell test; sounds more like a random number pulled from the air....
