Bitcoin Cash, Bitcoin SV, and Bitcoin Gold have already proven that while copying Bitcoin’s code is easy, copying its network and the trust built around it is impossible. The market has also given its verdict.

Meanwhile, instead of splitting Bitcoin, builders have turned their focus toward Layer-2 and sidechains. Forking is no longer seen as a solution — it feels more like a distraction.

You can still use Testnet 3 with no problems.

Price talk:

Testnet 4 has went from ~10 sats to above 40.  Very little support.

Testnet 3 is hovering ~100 sats to 130.  Few thousand bucks of BTC worth of support.

It's 2025, and the crypto market is reaching unprecedented heights. Bitcoin is approaching $200,000, Ethereum is targeting nearly $6,000, and institutional players like BlackRock are solidifying their positions. Yet, the real momentum lies beyond these flagship assets; in the altcoin market.

Overview of the Crypto Market's Growth Potential
While Bitcoin and Ethereum maintain their dominance as market leaders, altcoins are becoming the center of innovation. There’s no doubt that 2025 is shaping up to be a transformative period for the altcoin ecosystem.

Altcoins are capitalizing on evolving trends and creating lucrative opportunities for savvy investors. Even meme coins, which were once viewed as novelty assets, are demonstrating serious value and profitability.

The hunt for the "best altcoins to invest in 2025" is intensifying. You should consider investing in altcoins if you're looking for diversification, higher yields, or exposure to cutting-edge blockchain applications.

I got Ripple when it was invented and given away in a giveaway thread and later XLM when Stellar was launched., also in giveaway thread.
No idea about chia.

Actually got 105k Ripples and 5000 Lumens free from such threads I think.

Parted with the XRP when it reached almost $5 CAD in winter of 2017-2018 and bought houses but used the Lumens to launch tokens.


-MarkM-

I have committed to XLM for the long term, but understand why:

For one thing, I am not investing in XLM itself "per se", but rather in using XLM.

I use XLM the same way I use bitcoin, which is, to build buy offers offering to buy other things with it.

Sites like CoinMarketCap and CoinGecko and suchlike, sites that try to figure out what a thing is "worth", tend to look at the "buy offers" to figure out a "value" for a thing.

Thus if you want something to look "valuable" you want to make sure it has lots of buy offers offering to buy it.

Without "buy offers" it is not regarded by such "aggregator" sites as being "valuable".

Thus it is necessary to place "buy offers" on "exchanges" which is to say on "trading venues" in order to make "value" visible to the masses who use such sites to find what current "values" are.

Since buy offers might end up having to sit there untouched for years or decades or eventually maybe even centuries in order to be "deep" enough, "solid" enough, "dense" enough to be seen as "a strong buy side" implying lasting long term value, it would be utterly idiotic to try to build those "buy sides" out of fiat currencies, because over the years and decades and centuries we all already know from hard learned lessons of history that fiat loses value, so the buy sides we try to build out of fiat are doomed to just keep on losing more and more and more and more value over time.

That of course totally undermines the idea of building stronger and stronger and stronger "buy sides" to higher and higher and higher prices (values).

Thus it is better by far to build one's buy-sides out of something that retains value, and far far better even than that to build them out of something that actually goes up in value over the years decades and centuries.

Thus, bitcoin is the obvious thing with which to build huge stacks of buy-offers.

However, for a long time it tended to be the case that trading venues (exchanges) on which one could offer to buy things using bitcoin were centralised, custodial, they involved a third party holding both sides of one's trading-pairs.

Thus the usefulness of things like XLM: things that have built-in trading so that even though one side of a trading pair is some token you need to trust a third party to honour, at least the native-coin side, the XLM side in Stellar's case, remains in your own wallet even while being used in a buy-offer.

Note that my choice to use XLM for this purpose does necessarily mean in the long term that I need to build a strong buy-side for XLM itself, so if only for that I of course still need bitcoin with which to build XLM's own buy-side in order that XLM appear "valuable" to the aggregator-sites, and unfortunately currently that also means I still need to use a third party custodial "exchange" on which to build the buy-sides of the BTC/XLM trading-pair. ( Or of course issue BTC tokens there too myself so that BTC tokens I can trust exist there. )

But basically in real life history too few "exchanges" provided the trading-pairs I wanted to trade so I was forced to use softwares, ultimately including Stellar/XLM, that allow people to set up any arbitrary trading-pairs they choose to trade, basically acting as "exchanges" themselves, which is precisely what the original Ripple, on which Stellar was modeled when the current Ripple indicated it was diverging off into "big brother / 1984" realms, was designed and intended to do. (And in practice Stellar actually does rather well in my experience.)

What is merge mining?
Ethereum mining ended after the merge.

Why do you need to look for miners? You can mine your coin on your own several PCs?

I did notice that Mempool's explorer removed the Testnet3 depreciation message.

Surely Bitcoin Core will still pull v3, but idk... It's chugging along and doing its purpose pretty well, too.

Also, being maintained by Bitcoin Core is a pretty big deal for being listed on our exchange. *Hint hint*


Yes

https://altquick.com/exchange/market/BitcoinTestnet4 (Bitcoin, but you can trade other altcoins for Bitcoin and then into Testnet)

Is mining profitable for anything right now?

I know it used to be a thing a while ago but I guess its just way too competitive too make any worthwhile profit nowadays.

Can anyone shed some light?

We got this the first the you posted this.  Quit stepping into threads and adding your want to get your non-existent coin mined. 

Again, Saint, if you got the pool... I got some power: https://www.miningrigrentals.com/u/altquick
