iShares Blockchain Technology UCITS ETF
What this fund is
iShares Blockchain Technology UCITS ETF is an exchange-traded fund (ETF) from iShares, traded under the ticker BLKC (ISIN IE000RDRMSD1). One trade buys a whole basket of holdings, so your money is spread out instead of riding on a single company. At its core it is a focused, thematic fund: it concentrates on the technology part of the market, so it lives or dies by that one area rather than the economy as a whole. Underneath, it is about owning small slices of companies, so you share in their growth when they do well — and their falls when they don't. Its largest holdings include COINBASE GLOBAL INC CLASS A, BLK ICS USD LIQ AGENCY DIS and IREN LTD.
With about 55 holdings (the ten largest ≈ 66.2%), your money is diversified rather than concentrated in a handful of names. Its biggest country exposures are ~88.1% United States, ~9.9% Ireland and ~5.3% China. Its heaviest sectors are ~67.2% Technology and ~28.3% Financials. A focused fund like this is typically held as a smaller 'satellite' position around a broader core — a way to lean into one theme, not usually a portfolio's only holding. Its ongoing charge (TER) is 0.5% a year — about €50 a year on a €10,000 holding, taken automatically from the fund.
It is an accumulating share class: dividends are rolled straight back in, compounding your returns rather than landing in your account as cash. It holds the underlying investments directly (physical replication); it is domiciled in Ireland and UCITS-regulated, a European standard built to protect everyday investors and trades in USD. Its price has swung about 52.7% over the past year, which describes how much its price tends to move rather than whether it is good. It launched in 2022. Like any investment, it can lose value as well as gain, and what it did before does not predict what it will do next. (Fund data sourced from iShares.)
