Its is important to never forget what happened in 2013 in Cyprus. Yes, there will have been “dirty money” lost, but there will also have been people saving for a house, people moving house, inheritance, etc. all genuine reasons to have significant funds in a bank.
Let us not forget that money saved in a bank account is just numbers on a screen, and it is always best to diversify funds into a range of hard assets; land, property, stocks, shares, bonds, bullion, even cryptocurrency.
