It's hard to grow when you want to compete with bitcoin and other 100000 bitcoin clones, each of them with their own small changes over the original claiming theyre best. Wannabe crypto payment / monetary system is saturated in crypto scene, it cannot grow further than this unless it's heavily pumped but then you need to be lucky enought to exit in time. Projects that intend to have more usage than the simple monetary system will have much more success, like ethereum, biggest of them at this moment. And even if their primary goal isnt to be used as a monetary system, their added value from real projects will be a boost for it's usage as a payment system aswell, which will kill bitcoin and anything alike since, let's be honest, a cryptocurrency will never be able to hold it's value only by being used as a payment system against projects with real value from real tangible projects. What do i mean: 1. People claim bitcoin can be used as digital gold / payment system. Okay, but this all depends on it's perceived value, since, unlike gold, it has no usage at all if people lose their faith and dump it ( gold is used in industry, jewelry and so on), therefore it's perceived value will decrease to 0.
So, let's imagine what would happen: ethereum grows, alot of projects work on it's chain, therefore the token value is will grow alot, let's say 50$. Why would anyone bother to use bitcoin as a store of value when they can use ether, when it's value is backed by the amount of projects that work on it and not pure faith which currently holds bitcoin value high ?
I do believe monero will continue to exist, price will fluctuate but it'll remain the average joe who aimed low, same as litecoin. Or maybe not aim low, but lacking a bigger and better development team.
Leadership in crypto scene matters alot unless you aim to be a bitcoin clone. So far i'm impressed by ethereum development team. Don't get me wrong, i'm aware that they're getting rich while doing this, but atleast they deliver. Would be nice to see other crypto projects to aim higher and to be more ambitious, most projects out tehre don't deserve to exist, they're just a milk cows for devs.
Bitcoin and Monero aren't competitors. If you want to declare your finances on a public blockchain then use Bitcoin. If you don't want to declare your finances on a public blockchain then use Monero.
The global blackmarket will provide liquidity to the coin that best conceals it, and the global blackmarket's capitalization is not a figure to be sneezed at.
Bitcoin is useless for such purposes, as is Dash, Zcash and Ethereum.
So there's no competitional factor, just as long as Monero is technically and politically the best, which it currently is.
