Offline wallets are most secure, a good idea is to transfer just small amount from offline wallet to online wallet if you see online wallet necessary for making transaction often or get a hardware wallet which is cold wallet that you can use often for making transaction. If you need online wallet for making transaction, it is not good to use a mobile phone wallet, use a desktop wallet that you do not carry about like phones and that is safe from malware.

‘Crypto muggings’: thieves in London target digital investors by taking phonesThieves are targeting digital currency investors on the street in a wave of “crypto muggings”, police have warned, with victims reporting that thousands of pounds have been stolen after their mobile phones were seized.
One victim reported they had been trying to order an Uber near London’s Liverpool Street station when muggers forced them to hand over their phone. While the gang eventually gave the phone back, the victim later realised that £5,000-worth of ethereum digital currency was missing from their account with the crypto investing platform Coinbase.
In another case, a man was approached by a group of people offering to sell him cocaine and agreed to go down an alley with them to do the deal. The men offered to type a number into his phone but instead accessed his cryptocurrency account, holding him against a wall and forcing him to unlock a smartphone app with facial verification. They transferred £6,000-worth of ripple, another digital currency, out of his account.
A third victim said he had been vomiting under a bridge when a mugger forced him to unlock his phone using a fingerprint, then changed his security settings and stole £28,700,
In another case, a victim told police that his cards and phone were pickpocketed after an evening at the pub, with £10,000 later stolen from their account with the investing platform Crypto.com. The victim was using his phone in the pub and believed thieves saw him type in his account pin, the report said.
These mugglers will know that crypto transactions are not reversible and if crypto wallet is set up properly, it will be very difficult to trace the muggler after the attack. People should not be telling people of the bitcoin and altcoins they have because no one can be trusted, anyone can send someone to attack. This has just been the start, there are many other harmful ways there can be people that can be physically attacked to steal cryptocurrencies from them, some might lead to wound or beyond. Let us be careful.
