Why choose Kucoin?
I suggest Kucoin for multiple reasons, here are a few reasons:
There are a wide variety of digital currencies to choose from.
Quick deposit / withdrawal.
A large platform with good security.
Transaction fees are among the lowest in the industry.
Minimize the risk of hacking
Hacking your personal account is definitely risky. To minimize this situation, take the following precautions:
Have a long password and change it often.
If you just want to invest in Bitcoin, keep your Bitcoin in Kucoin (instead of transferring it elsewhere). They are backed by a large amount of venture capital funding and have built an advanced platform that minimizes the risk of your Bitcoin being stolen.
If you want maximum protection, you can also keep Bitcoin offline, perhaps on a USB drive that you carry with you.
