I almost need a step by step. (fucking hate asking). My goals: long term holding and secure as you described. Is $2500 too little to start?
naw guy you can start with any amount
heres what i know, ive got around 40k invested and im certainly not a professional so maybe others could add
your start amt is whatever your comfortable of losing which your not gonna lose but theres always that remote possibility i.e. nuclear war etc
cryptocurrency is just another assets class you can invest in other than the US dollar
there are also real estate, precious metals one can invest
i already have metals so i wanted to diversify with crypto
when i started there were only 3 coins you could purchase (btc, ltc and ethereum), purchasing these will allow you to purchase other minor coins or alt coins and there are numerous alts out there
first you have to access an exchange, in this exchange you can purchase coins, i started with coinbase and they required no identification to purchase but now you have to provide everything that is DL, credit card info etc. they want this so the government can get a piece of your action and tax you
CB may be your only option for right now so let me get back with you on if there are any decentralized exchanges out there currently
but in the mean time go explore CB
there is also a discord thread on crypto you should venture in
