What would be the top things you would advise on or suggest to someone whos thinking of buying BTC?
Mine would probably be;
1 Before investing, spend time learning about cryptocurrencies and blockchain in general
2 Dont look at it as get rich quick scheme, but as a long investment
3 Learn ways to keep your bitcoin safe and secure.
4. Don`t buy it, earn it.

we should get used to earning bitcoin rather than buying them

5. You also have to invest some money to invest so you can get a higher profit, dont depend on your income alone try to have more source of bitcoin.
Theses suggestions are being mentioned many times in the forum and i hope everyone know when to buy and sell bitcoin, enough knowledge can generate more profit.
