best in what way? if you're talking about risky but profitable then holding cryptocurrencies that have strong support. if you want something with minimal risk but far less return you're better off going with mutual funds.
There is actually nothing called "best" investment. Every investment carries its won risk and if you cant handle it you should steer clear of it. Trading bitcoin/fiat and altcoin are profitable according to me. Mining used to profitable at one time and not so at this point.
People in this forum also earn by using their skills and knowledge to work for others - freelancing. You can also try joining signature campaigns which are very popular, but make sure not to spam the forum but rather make proper constructive posts.
For the time being, there is more unity in the altcoins such as Ethreum or the Monero, that is the people people are buying them.
Don't plan for today, you have to plan for the long run. I dont want to comment about altcoins but i want to tell more about btc to you is it is very secured than other investment options, here you can earn by doing investments, trading, selling and mining. according to me more than any other way of investment btc is good.
I agree, the best thing about bitcoin is that offer you a lot of ways to make profit whether you like simple work like freelancing micro jobs or trading and investing and gambling there is always a way to make profit and it is always safe to use so investing your money into bitcoin is always profitable.
In recent times I made an investment with reputed gambling site which provided decent profits. After long gap, I made some returns like what I have done with cloud mining. Best investments are not always available, but when they are available we must make use of them.
