Interested in seeing if it’s worth all the hype. Been investing a small amount on PayPal but it’s seems just to trundle along - put in £80 in 4 different cryptos but seems to hover around £78 and goes down slightly and back up or has done for a week. Is it worth it? My neighbour was doing it but he major computers to do loads of data mining and he was making about £3000 per month but has stopped due to cost of electricity. What causes spikes in crypto?
