There are lots of ways to increase your profit and airdrop is one of that ways, but somehow not all airdrops are worth joining because some will end you up receiving shitcoins, so it would be better to always review their dev, because if it is a worthy airdrop then you might end up investing in it. And also try to join some bounties, some projects that offers airdrops also offers bounty its good in increasing profit.

First thing you need to do is to rank up your bitcointalk account,
After that you can start earning bitcoin through joining campaigns such as bounty campaigns and signature campaigns or try joining airdrops.
If you want a big earnings then try trading your bitcoin, trading is great but you need to invest first.

Surely advertising bitcoin in a television is a good idea in boosting the popularity and peoples attention on bitcoin, but there are lot of problems.
First, television advertising is really expensive.
Second, promoting bitcoin doesnt makes profit for those who pay the bill in advertising bitcoin, and more.

Maybe no one would dare to pay the bills in advertising bitcoin when there is no benifits in return.

Probably there is one cryptocurrency which has the potential of replacing bitcoin, and thats the ethereum, cause etherium is also increasing but it will takes a lot of years before ethereum will replace bitcoin.

If time comes that theres another cryptocurrency that will replace bitcoin maybe bitcoin will not be totally obsolete, im sure some people will continue using bitcoins.
