Just swap all your shitcoins for Bitcoin.
Bitcoin has been the most profitable investment of the past decade, and it looks like it also going to be the most profitable one of the decade ahead. If it maintains that rate of return, you only have to hold $1,000 in Bitcoin for 6.5 years it to turn into a million.
Till now bitcoin turned many into millionaires who had the patient to hold for a long time but with the price rallying a lot you cannot expect the same kind of profit like the earlier investors used to get. There are other coins in the market that rallied along with bitcoin especially coins with lower valuation and if you are holding those you could make a huge profit as well and some of these coins gave bigger returns than bitcoin.
Personally i do not trust holding the coins in exchanges let alone lend them.
