Well it seems now of days crypto has attention not massively but just enough to create a market (where if your smart) you can build a good nestegg. How? well if your savvy enough you could use your investment knowledge to create crypto wealth. The tools we have in place now can more than do the job. And I don't mean "we" as in any organization of traders but I mean the retail trader. Although decentralized it'a sort of not retail, but with enough money we can become the market makers (literally) and make decisions on where price action will take place and we can create movement that otherwise wouldn't work on certain options and equity trading. With the emergence of arbitrage crypto platforms it seems crypto investors have found bountiful means of ways to acquire more and more assets.
The pickle where in right now has many speculators saying Bitcoin is the backbone of the other alt-coins in the industry and they can only survive with Bitcoin. In a sort of way it's true, but Bitcoin isn't the end all be all and alt-coins don't need Bitcoin for price value as they are sort of same technology and don't need reliance on one another. It's a perk to be able to trade your alt-coin for Bitcoin, just because of the fact that Bitcoin has high value right now.
Remember these are just views of my own opinions and you can totally disagree but you can build a nestegg from alt-coins alone and still be safe in the future. As without Bitcoin things don't change as there is better code written in alt-coins nobody has even glanced at or heard of, that's what makes this industry so great "you have options on what you want to choose" this is what due diligence brings forth.
