it is so obvious that majority of the world is totally dependable on Bitcoin.
but I think that in anything we do we should try as much as having a plan b, there is nothing wrong if we invest in other business as plan b.
for example I have seen most men who are international staffs in an oil companies taking a huge amount of money at every end of the month not knowing that nothing last forever more especially money.
so am on the opinion that every Bitcoin miner should have a plan b of investing in other business to avoid the story that touch.
The world continues, the end of Bitcoin no be the end of the world, nothing go last forever normally so even Bitcoin no go dey until the world end. The title of your posts dey different from the body of your post as for the title you dey talk like say make we no invest for bitcoin but the body, na advice for us to buy Bitcoin you dey try talk. Majority of the world aren't depending on Bitcoin, Bitcoin never get any better share of the economy of the world self so we still dey far from dominating or making people to depend on Bitcoin.
Where you fit say dey dependant on Bitcoin na that altcoin market as na Bitcoin dey control everything wey dey happen dat side.Your post dey reason us say make we dey diversify and nothing bad to dey run am like that. All of us here know say we no supposed dey put all our eggs for one basket so as we dey make profits for Bitcoin or get better cashout for our other businesses, e go make sense say we dey Invest for other businesses as well and me I go say make dem be physical so Incase anything happen online we fit dey get physical cash to dey use hold body.
This one wey you dey talk about miners so, sure say no be mistake wey you make as na Bitcoin investors wey you wan talk (e makes more sense for the sentence). Sha Irrespective of what you're doing make sure you always have a plan B Incase A no deliver you fit get something to fall back on.
