Pros and cons
Lightyear
Pros
- Account fees of €0 and monthly fees of €0 keep ongoing holding costs low
- Inactivity fees of €0 suit buy and hold investors who trade at intervals
- Markets of stocks, ETFs and crypto give broad choice across shares, ETFs, bonds, funds and crypto
Cons
- Stock trade fees of $1 look pricey next to ActivTrades at $0 and XTB at €0

Pros
- Headline rate of 3.35% against a site median of 3%.
- Demand deposit accounts with no limit on monthly withdrawals.
- A linked credit card that pays cashback rewards.
Cons

Who each suits
Lightyear

Who should look elsewhere
- You want commission free share dealing on every trade, so XTB may suit better given stock trade fees of €0 against Lightyear at $1
