Distributing 10 to 20 pieces of different wallets is the smartest behavior. But to me it is impossible to have 100 bitcoins! It is that absurd and meaningless to discuss it. 
The fact is that currently there are very few users who have bitcoin amounts greater than 100 btc. So I think these tips will not give much benefit to many users lol. But it's a good idea to share it with lots of wallets. Of course it will be safer
