@fre2mansur my advise - don't buy anything for education purpose.
Education is a short time.
If you don't have crypto yet, try all steps "mining"-"wallet"-"exchange".
For example, use your laptop to see CPU mining (banano or other coins), telegram click bots, faucets (btc, ltc, doge and so on) and for less than a month you gain your first crypto and see difference in speeds, fees, difficulties.
