Thank you for the recommendations, will look into Trezor or Ledger.
What would you consider a invest line between not getting an hardware wallet and getting one, obviously if someone plans to invest 10k dollars in some coin, hardware wallet is a must buy, but where do you think is the line between "my portfolio is not big enough and spending on HW is too much for me because of that" and "I need to buy one considersing on how much I invested..."?

Also, if ERC20 tokens can use same adresses as ETH ones, can you just make paper wallet for each erc20 token, just as you would for ETH, same procedure? Do I even need to make them separately or can I just deposit my, ie. SONM on the same adress where I have my ETH, so in HW or Paper wallet, that all is looked as one wallet? Probably im not figuring that part right...
