There are many security issues with cryptocurrencies like bitcoin. The biggest problem is that it is very easy to commit fraud because of the blockchain technology which bitcoin uses. This makes all transactions irreversible so if fraud does happen it is impossible to figure out who did it and impossible to reverse and get money back. Another security problem with Etherium specifically is that with the DAO the blockchain was compromised leading to the creation of Etherium Classic.
