FolioCrypto tracks your crypto portfolio and the market data around it. It’s free. The simplest way to judge it is to take a look.

Sound familiar?

Your crypto is in a wallet. What you paid for it is in a CSV.

FolioCrypto links each withdrawal from the exchange to its arrival at your address. Your cost basis survives the move.

A wallet doesn’t know what you paid

Your address shows what you hold. The exchange CSV knows what you paid. A tracker that only reads your address sees tokens arrive, not what they cost you.

FolioCrypto puts the two back together

XRP position analysis in FolioCrypto: the quantity rebuilt from purchases is reconciled with the wallet balance and split across Xaman, Kraken, OKX and Binance.
Sample portfolio, after importing a CSV and adding a public address.

Three steps

  1. Import the CSV from your old exchange.
  2. Paste your public address: EVM, Solana, XRP Ledger or Nervos CKB. No keys, no control handed over.
  3. FolioCrypto matches each withdrawal to its arrival.

What happened in Europe

  1. MiCA’s transition period ends across the European Union. A platform without a licence must stop serving its European clients.
  2. Binance, without a licence, cuts off trading in France, Italy, Spain, Poland and elsewhere. Two million accounts in France alone. Withdrawals stay open.
  3. 70%of Binance’s EU withdrawals went to self-custody wallets, according to co-CEO Richard Teng. 30% went to licensed platforms.

No numbers to show you. Just the tool.
