I understand English very well and what I pointed out was correct about Barikui write up, I think your problem is you fine it difficult to comprehend a writing.
Now you have made same mistake by trying to explain to me what Barikui was saying now let me quote your explanation "Barikui is saying to start investing in bitcoin all you need is discretionary funds" now from this statement you said all someone needs to start a Bitcoin investment is a discretionary income, and I'm saying this could mislead a newbies who have gotten a little knowledge of backup funds in Investment, when a newbie wants to start Bitcoin investment and he knows about backup funds he needs it, not just discretionary income, we don't know when an emergency will happen so you guys should stop making it look as if starting a Bitcoin investment without a backup funds at first is good, an emergency can happen at the beginning or early stage of your investment so how will you over come it without a backup funds.
Backup funds is very much important, the only reason why we say you can start building your backup funds now is because they never had the knowledge of having a Backup funds now that they now have it is good they start building it a long side there investment, now this those not mean we should push same narrative to newbies, as a newbie before you start do well to have a little backup funds and then you can decide to build it alongside your investment or you start both at same time.
