MINER LIFE? And declining performance?

We ourselves have in the office miners (Antminer S9), which mined for 6 years and still work at full capacity.

• And those are machines that were manufactured 6 years ago.
• Manufacturing quality is constantly increasing, so machines produced today should “survive” even longer.
• But we don’t want to overhype it and therefore we still state lifespan “only” 4-6 years. Real tested lifespan (not just theoretical).

Does the machine’s performance drop after years?

• No it doesn’t drop.
• A miner with performance e.g. 100TH has 100TH even after 1, 2 or 5 years of mining.

Rather maybe You Mean ..:

• .. that difficulty (mining difficulty) grows and your 100TH miner will therefore gradually mine fewer coins?
• That’s true yes. But the machine will have performance 100TH both at purchase and after 5 years of mining.

To difficulty:

• Difficulty grows when the crypto price grows long-term (PS: the same applies vice versa).
• In reality, therefore, your miner in X years will mine daily, for example, half as many coins as today, but the price of these coins will be, for example, 2-3-4x higher.
• Your total daily profit (in euros) will therefore be, for example, the same or higher than today (everything depends on the development of the coin price and difficulty).
• And The Same Vice Versa: If the coin price in history fell long-term, people disconnected from mining, thus the mining difficulty also fell and your 100TH Machine thus Mined More Coins (those coins but had a lower price on the exchange).
