Nah over the course of the years I've learnt no alt coin is worth anything. If you want to invest in crypto stick with btc/eth.
This is complete bs and almost a cliche at this point. There's so much potential in a lot of altcoin projects to provide longterm solutions that in 10 years+ will still be in operation with their tokens being worth thousands of % higher than today. Case in point - BAT and Brave. If you want more just take a cursory look in the top 50 and do some research into what some of those projects are about.
If you've learned that only investing in BTC/ETH is worth doing "over the course of years" then you haven't been paying attention tbh. If the goal of investing is maximising profit (which it is) then take a look at the ROI on BTC over the last bull run compared to a cluster of the top altcoins at the time.
Saying that only BTC/ETH should be invested in is the same as saying that the only viable applications of crypto and blockchain are as a basic form of digital currency and as 2nd-layer smart contracts system. That's as insane as saying the only way AI can be used is self-driving cars and playing chess.
Ask yourself this: why aren't they using the default DAI and Maker system? Why do we need a new coin for each pawn shop?
Because almost all provide unique opportunities, and those that don't are competing against each other for prominence.
ie. Curve provides the lowest slippage for stablecoin:stablecoin trading.. traders, farmer/lp's, investors are an ecosystem of profit and income amongst themselves. Before Curve there wasn't a platform that focused solely on stablecoin liquidity pools, although obviously there are others where non-stablecoin:stablecoin could be traded with low slippage (still not as low though).
I was actually talking to the founder of Curve two days ago about some of the new products they're developing right now in partnership with a few of the other DeFi projects and I think that all involved are going to take off and be some of the best investments of this bull run.
As most crypto projects, only ~10% will still exist. Everything else will die.
I used to think that a few years ago as well, but over time I've realised that picking arbitrary percentages and saying that's how many will be left in the future is an unsubstantiated guess at best.
Realistically, anything that solves a real-world problem and is profitable will continue to operate. If only 10% of projects do that, yeah, only 10% will survive. But there's an equally likely possibility that 50% or more projects survive, especially being that the people behind those projects have a) the incentive to create legitimate startups that solve problems in order for them to make money b) continuous investment from the market, and c) 4 or 5 years (for most projects) of operation without disappearing and having that time to keep building out their infrastructure.. bearing in mind many of those projects secured more than $1M in funding during the ICO boom, and a still large number got more than $10M.
Any founders of those crypto projects could have taken the cash, dissolved the project and never worried about it again. They're still in the market, a vast majority have built teams and expanded their original scope of operation.
At the end of the day, logic always wins. In this situation its more logical for these projects to build something viable and then ride this bull run and the coming ones and disrupting their chosen field with a blockchain-based solution than larping around for 4 years without creating anything worth investing in.
