I am 19 years old man living in South Korea.
I want to invest in bitcoin for rest of my life, and I have 0.002 btc now. I want to keep it safe forever.
Someone told me that exchange is not safe because exchange can be hacked by hackers.
I am using software wallet called 'electrum'. I downloaded it from the official website 'electrum.org'
Is this safe wallet?
Sorry, I am not fluent in english. Please understand me.
You currently do not have much amount, only 0.002 BTC so it is advisable for you to save this amount in Electrum wallet on your desktop. It is safer than storing it on any web wallet or exchange but less safe than any hardware wallet or cold storage.
I would not recommend you buy a hardware wallet now because your total bitcoins amount is quite low but still I will encourage you to get the know how on how to setup Electrum on an air gapped device or how to setup multi sig wallets on Electrum. These things won't cost you extra but it will help you prepare and secure your wallet as you continue to increase your Bitcoin savings.
