For those who are interested
here is an explanation of how Bitcoin and the others work.
As for St James Place, they have the reputation of being a decent outfit but charging high. The stats show that 80% of fund managers fail to match the index which surely is the minimum you would expect. And the 20% that do is not the same 20% each year. But there is another issue. SJP was founded by Rothschild and Weinberg and invested their personal money. Then it was bought by HBOS who in turn were bought out by Lloyds, the latter being described in an investment magazine as the banking equivalent of the civil service. Huge corporate bureaucracy doesnt usually mean success.
I dont know about a 3 legged stool but certainly a two legged one makes sense with the two legs being property and investments / pension. But many have too much in property, quietly forgetting thats what their house is.
