Of course the investment would be better than gambling.
In some point yes
But it would be better if we start all of it from gambling.
You totally got this mixed up
Because we will already understand what it means to "bet". I think, if we start trading, or investment it is certain we are faced with a big gamble.
Clearly you dont understand what you are typing. Investment is not really a gamble if you know what to invest, besides you should be aware of the risk already if you put your money in an investment
For example, when the BTC price reaches such a value, do we dare buy it for speculation that in the future it will rise?
Nope but it worth the risk because with every risk there is a reward as well
