yes, it is important to always monitor the cryptoqurrency assets that you have now. I mean, so as not to miss the opportunity to sell coins that you hold when the price is high. for me, 2020 is a good year for the crypto market because the price of bitcoin has passed $ 10k and the other top cryptoqurrency is also experiencing good price growth.
We can see that the market as of now is recovering by looking at every price of cryptocurrency just like bitcoin, we can actually see that the price is recovering and rising as of now, we are all hoping for it to continue for us to experience bull run so that we can sell every token we are holding at a good price. Based on my own observation, as the bitcoin price rises up, it will affect any other altcoin to rise up in terms of price too, that is why I can say that bull run can happen anytime.
Since from the beginning I entered crypto space, and started opening accounts on different exchange, my coins are all still in there, and nevere had been decreased, so I am perfectly comfortable leaving them. They would surely send me an email if theres a problem, also I have out security measures, 2fa and just to be sure my coins are all safe from being hacked. Never had the experienced on being snatched by some weird exchange.
You are just lucky but not entirely safe.
2FA doesn't save you if exchange's got hacked.It only saves while others try to bruteforce your password or something like that.
This is what you should do to protect your wallet from danger and to prevent the worst to happen. You should secure your wallet by using that 2-factor authentication. Because through that, it can really secure your wallet from hackers. As of now, there are lots of hackers are everywhere trying to scam people especially to those not really informed in everything that is happening here, so I recommend to the new investors or the people who really want to start being involved with cryptocurrency, they better learn important things first.
