Hello guys with several wallets out there, I want to be sure make the right choice, because I have seen posts were members of this forum are complaining about some wallets and exchanges because of their unprofessional behavior.
So my question is, apart from electrum wallet which other wallet is the safest for long term holding of bitcoin?.

With the current reduction of price in Bitcoin, is it the best time to buy bitcoin or should I still wait for the dip?.
Though I have seen some post talking about "buy now or wait for the dip" but the debating answers got me confused, so I need the final clarity from you guys.
