I am a simply person, better safe and x2-3.
And sure I do invest my own money into Bitcoin, I do it aprox. 15% from my salary.
Bitcoin is main and safest investment in cryptomarket. Its good to hold only bitcoin but i think i am prefer diversify my investment in several altcoin because i am believe there potential altcoin can give us profits
In crypto investment too, in as much as we all believe so much in Bitcoin, Bitcoin alone cannot always be there for us, there are some cases where Bitcoin may not increase or meet our needs for trading, while other potential altcoins would do, we just need to diversify and ensure that the projects is also worth the risk.
