however remaining crypto-currencies became almost impossible for me because of the high cost involved and very low profit margin
what exactly is that remaining cryptocurrencies your talkin about because there are thousands of them after the bitcoin and bitcoin is the only crypto that are hardest to mine but for the remaining you can possibly mine them effortlessly but dont expect that you can get a good return because their difficulty isnt also hard anyway but that should be enough for you because you only wanted to try and experienced what is like to mine your own coin but if you want to make mining a serious thing you need to join or apply to a huge mining business or work hard to earn and buy the best personal miners .
