I've saved 1 bitcoin in my wallet, I'm sure bitcoin will rise, right now it's very appropriate to invest in bitcoin because the price is going down, don't waste this golden opportunity to change your destiny in the future.
Yes that's very true that its the right time to invest in Bitcoin as price of bitcoin is at its lowest compared to its price in last couple of months. There is no best time to invest in bitcoin other then right now. As far as saving in multiple wallets is concerned, I consider exchanges like binance as bet place to save bitcoin as chances of theft are rear in that case. I lost huge savings due to hack of my electrum wallet, since then I am saving my money in exchange.
