1 Before investing, spend time learning about cryptocurrencies and blockchain in general
I think one must also analyse what ever he/she has read and also, test the analysis on testnet before entering to actual investment.
2 Dont look at it as get rich quick scheme, but as a long investment
There may be many investment/portfolio mangers who may show you some scheme and say that they will trade for you. Do not get into such things. Also do not trust on others Bots if you have some strategy in your mind create your own bot.
3 Learn ways to keep your bitcoin safe and secure.
Always use safe wallets. I personally prefer hardware wallets specially Trezor. Do not store your funds on Custodial exchanges there are chances of getting hacked. I always prefer trading on non-cutodial exchnages like
CoinSwitch, Changelly, changenow as they do not hold your private key.
