A summary of the second half of 2025: It's incredibly difficult to be a diamond trader in altcoins. radfi was the first on-chain DEX for Bitcoin, with $rad fluctuating 15x. fspks was the first meme for Spark, with a 2x fluctuation. NAT, a Bitcoin byproduct, fluctuated 4x. This was followed by the National Day BSC on-chain frenzy, Binance Life, etc. And the privacy coin boom. ZEN, invested in by Grayscale (actually not a privacy coin, but it benefited a bit, with a 4x fluctuation).
