Probably not an antique more precisely rare and valuable goods, more precious than gold rods. When bitcoin reaches its limit, the bitcoin scarcity will be difficult to obtain and the price is very high. But with bitcoins that have reached a fixed limit amount will not stop using bitcoin.

I think it will be both valuable and possibly obsolete. Latter will depend on the core developers whether they manage to keep bitcoin up to date and relevant for crypto users

Indeed, i think the right word is scarce. Scarce because its limited supply and the price very expensive. I think when bitcoin supply reach at maximum, it will become valuable asset in digital world because no one want to sell it

I don't think bitcoin will be antiques because many people using bitcoin to buy items, shop online and send money online. There is a trending that also people use that's the trading many people using trading to make money online and some people that begin to trade make mistake and loss their money.

Yes bitcoin will be an antiques and very worth in the future with high prices also I'm sure. With so bitcoin will never be the main currency as has been much discussed. BItcoin can only be traded in the crypto market.

And when the mining more harder, some miner are move to Ethereum or another because they just gain little. Is that a sign that BTC will be replace by ETH?

I dont know maybe it will come. Because the algorithm for digging bitcoins is very difficult. As each bitcoin is dug, the difficulty increases. So the digger will need a lot of time to decode, it will take more than 100 years to dig up all the bitcoins. We all know that bitcoin is created by computer technology, always this advanced technology will be never old anyway. At the moment, the value of bitcoin is well-known for its highest value in crypto, also the demand for using bitcoin is getting more popular than others. Although it is not easy to predict whether bitcoin will be in the future, it still keeps in high value.

for now while the market value of bitcoin is very expensive may be we can compare this to antiques but we don't know what happened in the long run as years passing by if bitcoin is still be precious like gold or diamond.

Should bitcoin become Antiques? On the contrary it will be the climax of its development the most interesting is ahead.

Bitcoin is like a rare diamond to get it. Currently bitcoin every day the price is always rising slowly and it also requires the struggle to be able to reach 1 BTC in the long term. Hopefully I will get a lot of BTC in order to realize the wishes and dreams of my future.
