I'm using Europamine since 2018, when they started to sell hashpower, I don't think it's a scam because usually scam don't last 3 years.
Sunmining, Auroramine, Hashmonster and many others scammed in less than 2 months, Hashflare, Genesis, Europamine, Hashing24 are up, so not all services are scam.
I have seen some MLMs and ponzi schemes operate for more than 3 years but still end up scamming people. So the age of the service is no exception
If buying bitcoin costs me less than doing a mining contract, then I buy bitcoin, but if I have a mining contract that doubles my capital in a year, then I go mining.
I explain: if I invest $ 100 in a cloud mining service and the forecast is that after 12 months it has become $ 250 (like now on Europamine.com), I find it interesting.
If at the same time, investing $ 100 I buy 0.002 BTC but after a year, BTC has not increased by anything, I always remain with 0.002 BTC
I seek profit, sometimes cloud mining is better and sometimes it is better to buy BTC directly, it depends on the price of BTC and the cost of hashrate on cloud mining.
Lol, it's just a forecast. You ain't even sure if you will multiply your 0.002 BTC x2 after the said period. They could give you less or even exit scam. Meanwhile, if I just bought my BTC, I am sure I have my BTC in my wallet which will appreciate in value with time.
0.002 BTC remains the same, but the fiat value is what we are looking at. You will need a lot more USD to buy 0.002 BTC today than u needed to buy it 12 months ago.
