These coins adhere to the same strict cap as Bitcoin, giving them the same level of absolute digital scarcity:

· Bitcoin Cash (BCH): A Bitcoin fork that retains the 21 million cap and PoW mechanism, focusing on fast payments.

· Bitcoin SV (BSV): Another fork that adheres to the 21 million cap and aims to preserve Satoshi’s original vision with larger blocks.

· Zcash (ZEC): Known as the "encrypted Bitcoin," with a cap of 21 million and halving cycles, it uses advanced cryptographic techniques for privacy.

· Decred (DCR): With a cap of 21 million, it features an on-chain decentralized governance system that combines PoW and PoS.

· Horizen (ZEN): With a cap of 21 million, it focuses on privacy and interoperability.

· Bitcoin Gold (BTG): A Bitcoin fork with a cap of 21 million, aiming to make mining accessible using graphics cards (GPUs).

· Namecoin (NMC): One of the earliest Bitcoin forks, with a cap of 21 million, designed for a decentralized domain name system.

· JunoCash (JUNO): A newer privacy-focused coin with a cap of 21 million and halving cycles, mined using CPUs.

💰 Coins with a cap exceeding 21 million (up to 200 million)

These coins retain Bitcoin's core characteristics (PoW, a fixed cap, and halving) but have a higher issuance cap, offering greater liquidity in exchange for less scarcity:

· Litecoin (LTC): The "silver to Bitcoin's gold," with a cap of 84 million coins (4 times Bitcoin's cap), using the Scrypt algorithm and faster block times.

· Dash (DASH): With an issuance cap of about 18.9 million coins (less than Bitcoin's), it offers optional privacy features and instant transactions.

· Komodo (KMD): With a cap of 200 million coins, it uses a PoW mechanism with privacy features and delayed Proof of Work (dPoW) technology.

· Gridcoin (GRC): A unique coin with a cap of 168 million coins, used to mine scientific computing projects (BOINC).

💡 Important notes

· Monero (XMR): Although it is a popular PoW coin, it does not have a fixed issuance cap in the strict sense. Instead, it relies on a permanent "tail emission" to ensure network security, making it slightly different from Bitcoin in this regard.

· Other coins: You may find coins such as Feathercoin (FTC), with a cap of 336 million, or Litecoin Cash (LCC), with a cap of 840 million, but these exceed the limit you requested (200 million).
